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

[computer]

Yeah, I've heard something similar to that, but I heard it was California. That never made sense to me and I didn't believe when Intel said that, but if what you say is true about the silicon being shipped to the countries from the USA, and it's the TOLERANCES that do it, then that could explain why Malay's are usually better. I'd like to know more about how tolerances can affect CPU performance. I can certainly understand it in a mechanical device, but not a solid-state device.

EDIT. I think this is the Intel info I used. orders@mailbox.intel.com or call 916-377-7000. You can email that address and they'll tell you the RMA Ph. # if it's different from that one. You have to handle the RMA over the phone though. I had my new CPU in my hands FOUR DAYS after sending mine to them!

I have a question...
What is the deferens in running RAID 0 on this mobo with 2 SATA drives using Intel or Promise controller?

Thanks for any insight.

 

[computer]

Contrary to everything I've read, the Promise controller is faster as far as single drives go, I can't speak for RAID since I haven't tried it. I ran hundreds of benchmarks in all kinds of situations and the Promise controller has higher performance in everything except a test called "PerformanceTest" where they are almost identical. This is for the Raptor, AND IDE HD's. In the file copying tests the Promise is also faster. You'll have to just test it yourself to find out if the same is true for RAID.

This being my first real experience at substantial overclocking you probably have heard these comments many times but here are some observations with my experience on this board.

Voltage drop at the core plays a very important factor when running high intensity gaming and especially when running distributed computing programs. I found at 3750 I could surf the net and run office apps just fine, but run a game for any length of time or two instances of D2OL and she would drop out pretty fast unless you really ramp up the core voltage. When it was appearant that it would require dangerous voltages and excessive heat just to do so I decided it was better to settle for less MHZ.

I found the sweet spot to be with a voltage setting of 1.675 in bios at 3621MHZ, 192FSB (240@5:4)2,2,2,6 PAT on Turbo on, and was able to run gaming unlimited time and 2 instances of D2OL running 24/7 unlimited time. Obsrving voltage at core while running 2 instances of D2OL, a distributed computing progrma that not only taxes CPU heavily but also the ram, that the core voltage would drop approximately .1 volt. If I were to run at 1.650 or less in bios it would freeze after so many hours or even minutes depending on the set voltage. I think that is one reason why some peeps cant get thier Prime 95 to last long. Thier system can be perfectly operational under normal use but under that heavy load the cpu core voltage drops too far to remain stable at their high clock speed.

For me, I wanted max FSB at safe voltage under full load since this system runs 2 instances of D2OL 24/7 every day. At the same time the overall performance had to exceed what I would get at 220 1:1. I found under bench tests that my current setup is faster and more stable than at 220 1:1 Which was reaching the outer limits of my ram capability.

However if I were not running 2 instances of D2OL or intensive gaming I would use a lower voltage at core since the voltage drop would be substantially lower.

I dropped my FSB to 250, CPU voltage at 1.675 next one below 1.7 RAM settings 400Mhz or 1.1, DDR voltage at 2.85, AGP is about 1.6 i think and left everything else on Auto but will not run Prime95, fails instantly
i am using OCZ PC4200EL so i think its the CPU as i can run at 258FSB with CPU voltage quite high just below 1.8
but have been warned it is too high

Yes, but what does MemTest-86 say?

 

[ItsMillerTime]

Well, it's not my ram.

Question: if I use a 400fsb p4 (2.2A) with pc3700, would I set ram to 1:1?

There has not been much luck with the 400fsb chips running on these boards from what I have read. If it runs on the board, you do realize that the ram will be running DDR200 @ 100Mhz fsb.

 

[ItsMillerTime]

I'm just troubleshooting with it to see if my system will boot. I might have fried the 2.8c or the board.
I have a 2.4b in a Dell 600sc but my 2.2a is easier to remove and test with.

The system will only post once after the cmos is cleared, I can get into bios, but it won't post after I exit.

I dropped my P4 2.6 cpu fsb down to 240 for 3.12ghz at 1.625v and Memory at 5:4 for 192MHz at 2.85v at 2-3-3-6 and now have good stability. I ran Prime 95 all night with no errors. Here are my benchmarks using Sandra 2004:

Great info, thanks. What were your read & write MB/sec results for the hard drives? (random, sequential, buffered, etc). These are in the body of the results after you scroll a bit. These are what you can paste into Notepad or this form with Sandra '04.

 

[computer]

Your "CPU Arithmetic.....Dhrystone ALU 9237 MIPS" on your 3.12ghz CPU is slightly lower than Sandra's reference 3ghz CPU; like my results are LOWER than Sandra's reference 3.2ghz CPU and mine is at 3.4ghz. I don't understand that. I guess the P4C800 mobo has "weak" CPU benchmarks. My "Arithmetic Dhrystone ALU" is 9726 and its reference 3.2ghz (200mhz SLOWER) is 9858. Hmmm.....

EDIT: However, my CPU Multimedia results are higher than the reference CPU. Hmmmm again.

 

[ItsMillerTime]

Just tried the 2.2 p4, 400fsb; pc3700 was downgraded to 266mhz but I got the same symptoms as the 2.8c.
Guess it's mobo problem, maybe corrupted bios?
Has anyone else ran into this problem?
I'll check the manual for bios recovery procedures.

 

[computer]

What BIOS are you using now? 1014 is the latest, but note the Asus "geniuses" REMOVED UDMA 6 from that BIOS! So, for your Raptor if you have one.....will only run at UDMA 5 on the ICH5 controller. "Brilliant" isn't it. Probably why the Promise controller is faster than the ICH5R.

BTW, does anyone have v1013 of the 800-E Deluxe BIOS? I think it was Beta, right? I have it, but I'm not sure if what I have is release or Beta version.

Yes, but what does MemTest-86 say?

memtest has never failed on me
i presume you mean memtest that runs within Windows

 

[computer]

Which Memtest runs within Windows? The only one I know of, "Memtest86" boots from a floppy and runs in DOS.

 

[computer]

Can anyone please tell me how to interpret Quake3 Arena Demo results? I see numbers at the bottom but it doesn't say which is FPS. Maybe I'm not running the right thing, I just click "Demo", is that correct?
Thanks.

 

[hpfanatic]

Edited my drive results above, reran the tests.

 

[muppet]

there seems to be 2 different memtest version
i have been using the Windows GUI one
i shall try the DOS based one that runs on bootup

 

[computer]

Can you post the link please for the Windows GUI based MemTest? I'd like to check it out. I don't see it at the Memtest86 website.

 

[computer]

That's about what I get when I test a WD800JB. BLISTERING buffered speeds, but low sequential and random read/writes. I can't run the AIDA32 "buffered read" disk benchmarks when the drives are on the Promise controller. I get some kind of bizarre infinite loop in the negative figures. Also have the same problem with "Fresh Diagnose" with the "read" results. It says some kind of I/O error and even does it in this PC where I use a Promise controller card for my HD's. Has anyone else noticed this? BTW, AIDA32 has the BEST HD benchmarking tests I've ever seen. Real time graph representations and readouts at the right, and you can compare all your drives on one graph.

 

[muppet]

this is one i been using but i think the one that boots of floppy is better

i am currently using the ICH controller for my Raptor 74Gb but you guys are talking as though the Promise controller is quicker
what is the best HD benchmarking software to test which one is better for my setup??
I am using latest BIOS

I just mentioned that below, AIDA32. Takes "hours" to d'load it since their site sucks. I lucked out and found another link, but can't recall from where. "Planet mirror" is the links at this website where you d'load files from, so that may ring a bell for you. Now I don't really how "accurate" it is, but it certainly LOOKS awesome, and very accurate. It has several different HD tests.

All these tests I've been doing is showing the ICH5R MIGHT, MIGHT be better since it seems to have better AVERAGE speeds. I won't know until I read over all the data I saved and study it. This is on the 800-E Deluxe and with SINGLE drives.
