"Monty" (Dead Parrot Sketch...I love it) what memory are you using and what timings? The "tech" is the guy from OCZ that has been answering my email. (See my first post above again from 08/08/2003 2:08 PM).

Raymond have you tried to enable Command Per Clock?

Bupkus, keep your IS7. It's much faster than the IC7. All of your top 865 mobo's are faster than their 875 counterparts except for the 8KNXP.

I'm not new to overclocking, but I don't feel like playing around much and this system is alot snappier that it was with the Corsair I had. I wasn't able to turn on any GAT and had to stay at 2.4GHz with a 1:1 divider.

I take that back. At 5:4, I'm not quite 100% stable. It does crash and/or reboot sometimes yet. Mainly in Explorer or IE. I decided to put it at 1:1 and just run at 2.4. It's 100% stable in everything now. I turned GAT upto Street Racer and disabled CPC too.

I'm so tempted to get rid of this board instead of trying to find memory that'll work good with it. I had some cheap PNY PC2700 that I ran at 3:2 with no issues at all. But, I've had problems with Corsair (alot of problems) and now Kingston HyperX isn't quite stable. Amazing that an "enthusiast" board won't work with popular brands of "enthusiast" memory.

As far as ocverclocking, I like to find out what the cpu can do first, so I use the

3:2 memory ratio
easy memory settings like 2.5,7,3,3.
All of the GAT settings on auto or disabled.
lock the agp/pci bus at 66/33
start with default vcore
bump memory voltage to 2.8
bootstrap psb800

then start increasing the fsb. If you reach a point where it's unstable increase vcore one step at a time, up to a max of 1.65, but hopefully you will reach 250-275fsb before you need that much vcore.

Then once you're happy with the cpu speed, figure out how good your memory is and use the best combination of memory ratio, and other settings to maximize memory performance. Don't be surprised if you can't use the GAT settings if your FSB is very high, although some people are able to. Remember that even if you could use them it wouldn't make much difference.

There is no "default" selection for memory voltage. It started at 2.6 on it's own. Is that right? Is there any chance of burning out my HyperX if I use 2.8?

 

[computer]

NordicNINE what's the exact type of Corsair and HyperX you're having problems with and on what mobo exactly? The corsair TwinX PC3200C2 and Kingston HyperX PC3500 or PC3700 was among the memory I've been looking at for my soon to be IS7-G. Maybe I should scratch them and keep looking at the OCZ Platinum and GeIL Ultra Platinum & ULD.
Thanks.

 

[NordicNINE]

I have an IS7 (no G or E).

I have Kingston HyperX PC3500 (two 512MB)

I had Corsair PC3200 Value Select before. I wasn't expecting any overclocks on memory or decent CAS settings, but it wouldn't work at all at 5:4.

The Kingston seems alot better, but I still have some playing around to do. Maybe bumping the voltage will help.

I still would think I could run 3.0 with the memory at 5:4 since that's under the 433 it's supposed to be able to run at.
Maybe it's just the 5:4 multiplier since I'm doing 3.0 and 3:2 now fine, but the memory is running way under what it should be able to do.

I'll do some tests and see. Maybe 2.4 with 1:1 and the GAT stuff turned on is faster than 3.0 with 5:4 or 3:2 with GAT off.

Yes the IS7 may be faster if you can enable F1 and the FSB is the same as on the IC7 w/o F1 enable but that will almost never be the case. If you take 1 for 1 the same parts just the different boards the IC7 is faster. How do I know? I have both and have done alot of testing and my choice for my computer was the IC7-G and I put the IS7 in my kids machine. It is easier to get the F1 (or any other GAT) option to work on the IC7. Using those options put a strain on the NB and the IS7 is just an OC'd 875 NB. Yes you can get one with a good NB but if I had to do it over knowing what I know now I would have not bought the IS7 and got the IC7 from the start. I still think the IS7 is the best bang for the buck though.

If so that seems wierd.

Well, on my Kingston HyperX, I can get it to work fine at 250 fsb & 3:2 ratio, but not with a 5:4 ratio.
It also works fine at 200fsb & 1:1 ratio.

The best I've gotten is 250fsb, 3:2 ratio, CAS settings of 2-7-3-3 & Street Racer GAT (all suboptions (including CPC) set to Auto)
I have the memory at 2.8v to do this. I will start lowering the voltage to see how low I can go and keep these settings.

This is exactly what I am trying to say. In theory your memory should work @ 5:4 250fsb if it will work @ 200fsb 1:1. It's the same dam DDR400 speeds. But for some reason some memory sticks just don't like the divider. Is it a BIOS problem or is it a NB problem? It's pretty crappy when you are trying to tweak your system and you get it all working at 1:1 and then try and use the 5:4 or 3:2 divider and the dam thing just beeps real loud knowing full well that the FSB on the DDR is below spec. Then you stick diferent memory in and all is well @ 5:4 but 1:1 won't work at spec. Don't get me wrong I would never go back to an AMD box now that I have got my memory problems (BIOS/NB probably) resolved but it took a while to work out the kinks.

will this GEIL ram work with the IS7?

Title says Samsung or "other". They are selling OC'd memory (granted that is what most are doing but I prefer quallity). I would stay away and buy name brand so the warantee won't be a problem. I can highly recommend the OCZ stuff.

 

[phatj]

check out my edited post oriion, how about that Geil ram?

The GEIL is some decent memory however, you should be looking at the Dual DDR kits if you want to run in DC with the best results. DC memory are matched pairs. If you just buy two different sticks the chances that both will do the same speeds are pretty slim. If you look at Newegg they have the Geil PC3200 2X512 2-6-3-3 Dual channel kit for $199 with free FedEx shipping these should easily hit the PC3500 speeds as they are rated at 2.5-3.1V.

What is Ultra DMA Mode 2? I'm asking cause I'm having some trouble with ripping slow with a DVD burner in this hot new machine.

That is what most CDRW/CDROM drives run at. Are you running winXP? If so remember to disable the ms burning feature.

This may help some of you if you missed it. This is from the Anandtech review of the 865/875 roundup, the IS7 info:

Just like the IS7, the IS7-G is yet another motherboard that has successfully mimicked PAT (Performance Acceleration Technology) code previously exclusive to 875P motherboards. As a result the IS7-G is not only slightly faster than every 875P motherboard we've tested but, ironically, also faster than ABIT's own 875P motherboard, the IC7/IC7-G. The procedure for reaping the benefits of PAT-like performance are the same for the IS7-G as they were for the IS7. That is, first make sure your memory timings are as reliably aggressive as your modules are able to withstand. Then, enable the "PSB533" setting under "N/B strap" if you're using an 800MHz FSB processor. After that enable the 1:1 ratio along with the "fixed" option for your AGP/PCI bus. Finally, enable the CPC (Command Per Clock) in the Advanced Chipset Features section. This only applies to users that will be running their IS7-G at stock speeds, if you're overclocking (especially past 250MHz FSB) make sure you use change N/B strap back to PSB800 so as to not max out your memory too quickly. A 3:2 DRAM:CPU memory ratio is usually your best bet past 250MHz FSB if you don't have expensive memory rated higher than PC3200 (DDR400). Otherwise 5:4 is still possible with high-speed memory validated at DDR433 (PC3500) or DDR466 (PC3700).

PhatJ I'm awaiting an email from GeIL, I asked them that same question as well as any other other issues with other 865/875 mobo's. I'll let you know. The GeIL ULD series and Platinum Ultra series is better than the Gold, plus they are DC kits, and they are all CAS2 up to PC4000. The PC4200 is CAS 2.5.

Orion I was going by the sites that have compared the IC7 series mobo's to the IS7 series. The IS7 is always faster expect for two tests I saw from the link of that review above where the IC7x beat it. The test starts here . The two tests the IC7x was faster is the "High end workstation performance", "SpecViewperf 7.0-DRV-08" and "SpecViewperf 7.0-Light-05". They were using the settings in the quote above for the IS7. If you can set yours to those settings, please let us know how that affects its performance, I know many would be interested. I haven't gotten a 865/875 mobo yet, and I've pretty much decided on the IS7 or IS7-G. I first considered the IC7-G, but since I don't need CSA LAN, and the IS7 was faster (using correct settings), the IS7 seemed to be the more appropriate choice.

 

[IntelInsideIdiotOutside]

Hhhmmm wtf.

I got my IS7-E with a zalman cnps7000cu cooler and a pair of TwinX 256mb memory modules from Corsair. I havent tried overlocking the 2.4c yet cause I get like 45,5 celcius 'idle' atm. Is this normal? I've flashed the latest bios with flashmenu. First time I installed the zalman I used Articsilver 2, second time I used theirs.

Before this I had an Asus P4B533 with a 1.6a pentium 4 and the stock heatsink plus cooler and I ran at 1600mhz at 32 celcius or something. hmm i'm thinking this sucks! Input please :|

 

[computer]

I currently use a P4B533 as well, and I'm running on it a 1.8a (Northwood 512k) @2.4ghz it never has gotten above 100°F under heavy load (it's usually about 85°). Stock retail HSF and a thermal pad. It would run cooler with HS compound as I have later found out several times. (Case in point with that is a customer's PC here behind me I'm building (S370) and just to check it out to be sure it works first; I put a Celeron 366 on it that already had a thermal pad on it). HUGE Leadman HS w/dual fans and a 3M thermal pad was 105°. I removed the pad and it went to 111°+ and climbing so it shut it down. I put some cheap white HS compound on it and it's 100°). Still rather high....I guess it's just the mobo's characteristics or different thermal diode.

Do you think your temps are high? I haven't used an 865/875 mobo yet, but 45.5C is only 114F which sounds fine. If you want it cooler, experiment with your HS compound. Don't ever use those thermal pads that come with HSF units, not even the pad that's on the retail Intel HSF. The stock pad on my current HSF unit is fine, that's why I've never replaced it, but when I get the new mobo I'm putting 10% silver HS compound on it or something similar.

 

[IntelInsideIdiotOutside]

Oh cool thanks for the input computer!

you know what, Im gonna remove that zalman and try the stock cooler and be back to post what happend.

hhm its now very stable at 45 celcius.

by the way a 2.4c runs hotter then a 1.6a (standaard)?

 

[computer]

I haven't used my 2.4C yet since I don't have the mobo yet. So I cannot yet say what it's temps are. Your stock retail HSF probably isn't going to be as cool as the Zalman (although I haven't seen that Zalman) it would probably stand to reason since it's a 3rd party cooler used to supposedly replace the retail Intel HSF unit it is probably going to be better. You may want to experiment with thermal compounds first.

[IntelInsideIdiotOutside]

lol the thermal compound from zalman is almost done, think im gonna save it for later and use the articsilver 2.

oke but this is even funnier now. I've put in my old 1.6a (running at standaard speed) and winbonds telling me its 50 celcius!

so it must be the is7 acting up OR the asus p4b533 wasnt reporting temps good.

 

[computer]

Are you comparing the same 1.6ghz CPU in an IS7 and in the P4B533? If so, I doubt you can compare the two since the CPU probably isn't going to run the same temp in both, or the thermal diodes may not be the same. To actually be able to compare the two you'd need some external temp. probe to check the temp's on both.

 

[computer]

Isn't the 1.6 P4 a 400mhz FSB CPU? If so, the IS7 isn't even supposed to support it. All they list is 533/800mhz bus CPU's.

 

[IntelInsideIdiotOutside]

Yes thats correct. But I have the IS7-E, this board also runs at 400 and 533, so my old 1.6a runs on it.

Oke. I got the stock Intel cooler running now with articsilver 2 and winbond gives me around 53 celcius with the 1.6a.

So on the Asus P4B533 I get around 32 celcius "idle". And on the IS7-E I get 53 celcius "idle". With the same 1.6a. I must be doing something wrong or abit and asus are pulling our legs here lol

 

[IntelInsideIdiotOutside]

ppfff 2.4c "idle" stock hs and cooler 48 celcius. Im confused :\

 

[Tom]

The Abit IS7 and IC7 give higher temperature readings than many other boards, by 10-15c. You have nothing to worry about with idle temple of 45c. I also have a stock Intel HSF and a Zalman 7000cu, the Zalman runs a few degrees cooler, maybe 5c average.

I'm using 2 256m Samsung DDR333 pc2700 memory sticks. Running at 280fsb, 3:2, thats roughly DDR370.

Orion- I understand what you are saying about pc3200 memory running 1:1 at 200fsb and not running 5:4 at 250fsb seeming screwy. I still think it's most likely the memory is marginal or has built-in timings that are too aggressive to run right dual channel at higher FSBs. One possibility might be that even though using the 5:4 ratio it would seems like you are putting the same demands on the memory, that actually since the processor sub-system is running at 250fsb it is wanting to access the memory too quickly in some way, despite the ratio.

Or as you say it could be that some Northbridges are able to work better at 250fsb than others and that's the issue.
