*** Official ASUS P4C800/Deluxe (875P) Thread ***

[computer]

GNY, why PC3700 Gold Rev. 2? What can you tell us about it? According to their site, it doesn't look as good as the PC3700 Gold #1. Rev. 2 is CAS 2.5 and what they had for the original PC3700 Gold was CAS 2. (PC3700EL is "Gold"). PC3700 Gold Rev. 2

i dont want to overclock at all but what are the best settings for my ram and the timings i need to set all of tehm thank you and have a graet holiday to all.

Hello drewdogg,

I would try using the same settings from the post I made a few posts ago (the ones I suggested for 1ManArmY) as a good base for your machine as well. Once you know you are doing fine with those settings I would then drop your memory timings to the 2-3-2-6 8 that this memory is suppose to be able to do.

What are you set to right now for FSB and Memory Timings?

Xeon, Merry Christmas to you sir !!!!! I have ordered some new memory from OCZ. I called them and they recommended a New product just out. PC3700 EL Revision 2 I have a gig of it on the way. Also a new Heatsink and fan. I running the new Intel one with the copper slug in the middle of it. I may need to give it a good blowing out. As I said Happy Holidays to everyone out there and I will keep you updated.

Ahh glad to hear you got some new OCZ coming! That particular set will do a good job for you, better than the cas 2 memory because your running one of the Faster cpu's (3 Ghz), the Cas 2.5 will allow you to get a faster FSB out of them and give you some good performance to boot.

I wasn't clear from your post if you had ordered a new Heatsink or if you were just saying you have one of the newer Intel HS and Fans. If your not going to Overclock that's probably fine but if you are going to overclock then I would highly recommend you get a better HS and Fan, since it's probably why your running some higher temps under load.

Let us know how that new OCZ RAM does for you!

Happy Holidays!

 

[GNY]

Xeon, I will let you know how the Memory works out. I have the newer Intel Heatsink with the copper Slug in it. I ordered a Zalman for right now. I did not want to pull the board out right now. I have 5 or 6 machines to do and just don't have time to pull the board out to put the SP-94 on right now. Have a great Christmas!!!!!

 

[GNY]

Hi Computer, Merry Christmas, I called Tech Support at OCZ and this is what they recommened. As you can see Xeon has posted on the subject also. I have a 3.0 and the rev 2 will work better with the high speed processors. We will see it should be here Friday. I will keep you all posted. Happy Holidays !!!!!!!

 

[computer]

Same to ya! :gift: :music: :beer: :wine:

I was curious as to why OCZ recommended that. In your case, you won't be able to get as high of a FSB as a 2.4C can, so you'd want memory with tighter timings since you can't really benefit from fast memory the way one can with a 2.4C. PC3700 is DDR466 which would be 233mhz bus and 233mhz bus is about absolute tops for a 3.0ghz which would be 3.5ghz. Most are getting about 3.2-3.3ghz from them which would be 213mhz-220mhz bus, which would be UNDERclocking your memory since it is 233mhz spec'd. Going from that and assuming you don't get a SUPER 3.0ghz CPU that will do 3.5ghz+, you'd be better off with PC3500 with really fast timings.

I thought you were using a 3.0ghz, but your sig. file says 3.2ghz. So, if it's 3.2ghz then what I mention above goes even more so. PC3500 would really be better for a 3.2ghz. That's DDR~433 about 216mhz and you'd need to run the CPU @3464mhz just to run PC3500 memory to spec. Actually in your case with a 3.2ghz, the new Mushkin Level II PC3500 is the fastest @PC3500 speeds AND at PC3200 speeds. Check out the memory reviews at Anandtech. It was faster than ANY OTHER memory, even OCZ @ DDR433 & DDR400 speeds, which is what you may have to run it at. If you don't want to O'clock, then it's certainly your best choice. Even if you do want to try and O'clock, it will still be the best due to the limited bus speed you get from a 3.2ghz P4. Mushkin review link.

That make sense?

Have a good one guys! :gift: :music: :beer: :wine:

[Amused]

Yeah, I have to agree with Computer. The Mushkin Level II PC3500 can do the tightest timings.

At 400 FSB I had it stable at 2-2-2-6 (vdimm at 2.75).
At 417 FSB I had it stable at 2-2-3-6 (vdimm at 2.75)
I now have it at 450 FSB and it is stable at 2-2-3-7 (Vdimm at 2.8)

That's the tightest timings I've seen at with a 3.2 at 3.6. And from the nasty remarks I've received in response to posting my benchmark scores in the General Hardware forum and Video forum, I'd say it's damn fast. People are pissed because I'm beating people with much higher FSBs, but much lower timings or people with high CPU over clocks and seriously low dividers.

 

[GNY]

Computer, I"m running a 3.0 and I"m running 227 right now with HyperX PC 3500 at 2.5 4 4 8 with PAT Enabled. Running 2.85 on the Vdimm and That is about the best the memory will do. Memory is running 453. I have a friend that is needing new Memory for his machine so I"m experimenting. I told Tech support where I was running at the time and this is the Memory they recommended. We will check it out and see. !!!!

 

[computer]

Hey that's pretty good for a 3.0ghz. Is that at 1:1? Probably not with that PC3500 memory. If not, then you would indeed be better off in this case with GOOD PC3500 that will do DDR453 1:1 (Check that link to see which PC3500 if any will do that), if none, then the PC3700 would be best. A quick check of that link again says the Mushkin I mentioned will do DDR458 in this mobo, so that may still be your best bet.

 

[computer]

Amused, I think you mean "DDR400" instead of "400mhz FSB" (and so on), right?

 

[GNY]

Computer, That is 1:1 Buddy !!!!!!!!!!!!

 

[computer]

Ok.......so then why do you need new memory!? What you've got sounds perfect, unless you're sure the CPU will do more and you're sure the memory is the limiting factor. If you can get faster CPU speeds @ 4:5 or 3:2 (or whatever they are, I forgot) then faster memory would probably help you.

Well, it is 400 FSB x 2. And I'm setting my clock speed at 200-225. So that's x2.

It's all so confusing. My BIOS has me adjust an FSB that starts at 200. My Memory is rated at a multiple of 2x that number. And my processor is rated at a multiple of 4x that number.

I miss the days when everything had the same bus speed.

 

[computer]

Yeah, the CPU is "quad pumped" and the memory is "Double pumped" (Double-Data Rate = DDR). An 800mhz bus CPU is really 200mhz bus. Would be easier if they just called it "200mhz quad pumped bus".

Merry Christmas guys . (Cute game). Now, time for the family.

 

[drewdogg]

i have corsiar twinx1024-3200llpt what would be teh best timings for it to work perfectly stable no issues and the violtage for it also my cpu is 3.0c 800 fsb no overclocking thanx a bunch

i heard the best would be 2-3-2-7 ddr voltage 2.75 any ideas thanx

 

[newb54]

I am building my 1st computer and I was pretty sure I was going to get this mobo until I read this thread. Here is what I am looking to build:

CPU: Intel P4 3.0C 3000MHz @ 3000MHz
Motherboard: Asus P4C800-E Deluxe
Memory: 1024 MB of Corsair XMS pc3200
Video Card: ATi Radeon 9800Pro
Storage: 2x Raptors 36.0 GB @ 10000 RPMS (in SATA RAID 0)

The problems with Corsair memory and RAID I read about are kind of scaring me off, have the newer bios sorted these issues out or should I go with Gigabyte or Abit instead?

 

[computer]

Drewdog: it's pretty much what we've been saying for months now.....it just depends on what EXACTLY you have. Each chips are going to be different and only you are going to be able to ascertain what the best timings are. You always want the memory voltage to be as high as the mobo can go, 2.85v, this will give the greatest stability and I've never seen any good memory that would not work with 2.85v. With that memory (PC3200) you may not be able to O'clock much @ 1:1, even with the low potential bus speed of the 3.0ghz, so you may have to go with 5:4 or 3:2 (that's 266mhz and 320mhz in the BIOS I think) which will hurt your performance. First see how fast the CPU can get @ 1:1, then change the DDR speed to 5:4 and 3:2 and see if the CPU's FSB can be increased anymore. If so, you're better of with faster memory. As for the timings, just keep lowering them until you have stability problems in benchmarks or errors in Memtest & the WMD program.

& Newb54: I wouldn't go with this mobo. I'm about to buy an IC7-G, IS7-G or 865PE Neo2 FIS2R because of the bug with the Promise controller/ICH5R on the E version running the WMD program. It doesn't appear Asus cares about this serious issue since they still haven't done anything about it. If you really want this mobo, then go with the NON E version since it apparently doesn't have this memory error issue. You're also better of with a 2.4C; it's much cheaper and you can get a higher FSB with it giving you more memory bandwidth. Tests show that a good 2.4C will O'clock about the SAME as a 3ghz (only about 100mhz higher with the 3.0ghz, which of course you can't tell he difference)! So since you'll have a higher FSB with the 2.4ghz giving you more performance, and it's much cheaper, it's a better deal. Unless of course you get a shoddy 2.4C like I did that won't do over 3.0ghz.

 

[drewdogg]

Okay i got my corsair DDRAM 1GB TWINX1024-3200LLPT
i can only run it at 2-3-3-6 with 4 bank i cant run it at 2-3-2-6 with 4 bank why not it supposed to work with that
i got my ddr ar 400mhz
and my voltage 2.75 and i tried 2.85

 

[GNY]

Xeon, I hope you had a wonderful Christmas. I got my memory today. Hope to get it in tonight !!!!

 

[rpr]

Well, I just got my new P4C800-E Deluxe (rev 2.0) up and running w/ my new P4 2.4C CPU (week 32, m0 stepping). So far, I'm pretty happy with my results, but as with any overclocker, I hoped (and will try) for better.

I've maxed out at just over 3.0 Ghz with my memory at 1:1, and just under 3.2 Ghz with my memory at 5:4.

The only other thing I feel I can really look at to get much further is my BIOS. I am currently running what it came with out of the box, which is the 9/03/03 version. Anyone have any thoughts on whether the 10/14/03 BIOS will improve my overclocking results?

 

[computer]

I don't know the BIOS revisions by date, only by code. 1014 is the latest last time I checked and it's no better o'clocker than 1008 or 1009. If you can o'clock more at a lesser setting than 1:1 then your memory is your weak link. What are you using? My 2.4C will only do 3060mhz at ANY memory setting. (BTW, Intel is taking it back, I'm RMA'ing and I sent my memory back yesterday, RMA'd it as well).

DC memory in kit form is always 2 sticks, at least I've never seen it as 4 that I can recall.. That's a problem which I never really thought of until now. When you use 4 sticks there's a greater chance of all 4 not being matched or equal. 4x256mb is just too expensive for me so I went with 2x256mb for now, and was going to be another 2x256mb later. I'll probably run into the same problem of not being able to run as good as timings with only 2 sticks. However, 4 sticks is going to give you better performance than 2, so the extra performance bandwidth wise is evidently more important that any timings you may have to raise. All benchmarks show a great improvement using 4 sticks over 2 with 4 DS sticks being the best. Also keep in mind that from what I've heard from review sites, you cannot enable PAT with 4 sticks of memory! I've repeatedly asked here for someone to verify that that's running 4 sticks but they won't. You can still enable it in the BIOS, but when you open CPUz it shows PAT is off. Still performance is better so evidently again, the extra ooomph you get from 4 sticks is greater than 2 with PAT activated.

 

[Amused]

OK, here's a weird one. My mobo has started beeping every so often when I play a game (about once per game of BF1942 Desert Combat, if that). No crashes and this setup is Prime95 stable for 10+ hours.

Any ideas?

 

[computer]

What are your temperatures during this time? CPU, board, video card, sound card, power supply, everything. You'll probably have to use temperature probes on some of these. If you have none, then the ole' "finger" will have to do. I've heard of odd behavior before (as I'm sure you've heard) when components overheat, but I don't recall ever hearing only a "beep". I'm not a gamer nor have I tried Prime yet, but unless Prime stresses the video card & mobo then I would guess your video card or mobo is getting stressed or too hot from the game. The beeps may be a warning.

This doesn't surprise me with 4 sticks of RAM. It will lower your chances of getting tighter timings on your memory and also FSB. This occurs because it's tough enough to match 2 sticks of RAM let alone 4 and the stick that has the least potential (weak timings and FSB capabilities) will be the one to rule. It's unfortunate that it works this way but that's the reality of it.

If your sticks of RAM are double sided your going to have another problem. PAM/PAT will automatically be disable when your run 4 sticks using this Motherboard. If you have single sided RAM then this won't be a problem.

My testing has shown that your better off using only 2 sticks of RAM with this motherboard if your running double sided RAM. When I say better off, I mean overall performance is better with two sticks due to the slowing down of the bus because of the lowest stick of RAM rule. Both FSB and timings suffer in all the combinations I've tested and I even had hand picked modules that were fast sticks of RAM and this always proved to be the case.

Sorry to give you the bad news but you are much better off with 2 sticks of 512 RAM then you are with 4 sticks of 256 and it's primarily due to the matching of the RAM. If you could get or find perfectly matched RAM, then you would be better off, but in my opinion that's a pipe dream, especially when you consider that it's hard enough just finding or getting 2 sticks that are matched properly.

What I would do drewdogg is go ahead and keep your timings at 2-3-3-6 and raise your FSB as high as it will go without causing Memtest-86 and Prime95 errors and then try to lower your timings some more on the memory (if you can). I know that those sticks are suppose to do 2-3-2-6 but not all sticks are created equal and with 4 sticks being used it makes it even harder to get the tighter timings. Raising your FSB I think is going to be your best option in light of the information you've given.

Catch you later.

Hiya GNY!

My Christmas was phenominal, I hope yours was as well! My wife got me a new RC Helicopter (Hirobo Sceadu EVO 50) and I've been spending a good amount of time building it these past few days.

Glad to hear you got that new RAM, let me know how it goes for you. You can also reach me at (xeon AT xshellr8 DOT com) if you'd like to discuss your new setup in a more direct manner.

Can't wait to hear how well this RAM does for you.

Talk to you soon,
