If i raise to 215x13 at vcore 1.65v, then it will not even boot to windows. I do not think it is a problem with memory because memtest will run fine. Is this a problem with the cpu or the motherboard? Or am I completely missing a very important setting in the bios? Any help would be appreciated.
--------------------------------------------------------------------------------


I updated my bios to 1.5. That didnt help much. I also tried disabling the last two GAT settings. That didnt seem to work either. I tried running my computer with only one stick of ram. Prime95 doesnt fail immediately at 210x13 but it sure doesnt seem like its completing any iterations.... although the computer does stay running. It does this with both sticks of ram so I dont think one stick of ram is bad. Any suggestions as to what I should do now? Any help would be appreciated once again!

Try manually setting your memory timings. Set them to 3-3-3-7 and see what happens. As I have stated on pg 7 or 8 there does not seem to be very much difference in performance when changing the memory timings with the 865 and 875 chipset. Set the the PSB to 800 and run 1:1 at stock speeds ie 233mhz if it does not boot then I would say either you got a bum P4C or the memory is not compatible.

ive got about 500 bucks to upgrade
and was gonna pick up
an IS7-E
a p4 2.4ghz c retail
and a pair of
OCZ DDR 512MB PC-3200 Performance Series w/ Copper heatspreader, performance memory for PC enthusiasts, CAS2.0 DDR 400Mhz memory, Lifetime Warranty -OEM, OCZ400512R2.
all from newegg

i know the memory isnt 3500 or 3700 but shouldnt i still be able to reach above 3 ghz on this system from an overclock?

i have a very cool case and im hoping most of the early memory issues will have been fixed this time by Abit

any feedback is appreciated
thanks

The chances are excellent you will be able to overclock to 3.0-3.2g, or higher. With that memory you may need to use a 5:4 memory ratio, which in my opinion isn't a big deal.

 

[porkbun]

If you plan to get some GeIL PC4000 Ultra Platinum for your IS7 board, read my case before you do so. I just got some, and I am not happy. So these two sticks are rated 2.5-7-4-4 at DDR500. Fine, they do work at 250 MHz. They even work when set to 2.5-5-4-4 at 2.8 V (zero errors in Memtest). I was using the 800 MHz strap with the 1:1 ratio. All GAT settings were Auto. However, I am unable to run them using ratio of 3:2 (200 MHz) or 5:4 (240 MHz) at an FSB of 300 MHz. Note that 300 MHz FSB is OK with my IS7, as I had been running 300:200 with another pair of GeIL for over a month and never had a single problem.

Just my little experience. If you guys know how to solve my problem, please enlighten me. Thanks!

Btw, I have seem somewhere that someone reported good results when they are used with the IC7.

As it turned out, the memory timings were the problem after all. Thanks for all your help orion! Although... I still cant get prime95 to go on 250x13. When I look in cpu-z after booting on 250x13, it says that my memory timings are 2.5-3-3-7... despite what I have set in my bios. That could be what is causing prime95 to crash. How did you get your board to run 275? haha. Arent alot of people having trouble getting past 250 running async? Does disabling the last two GAT settings help alot? Thanks for all your help!

Can someone help me set my BIOS for max performance, please?

IS7
P4 2.4C (Malay)
2x512 GEIL DDR RAM PC-3200 Value 400MHz Ultra- CAS 2.5, 2T
GF4 Ti4600
WD 80 Special Edition

I got the CPU to run at 3.0 by raising ext clock freq @ 250/70/35 with N/B Strap = PSB 800.
GAT on auto

My 3DMark 2001 score is 13859. Is that good or just decent?

I'm a noob at overclocking so please help.

Keep your strap at 800. Set ratio to 3:2.
Fix your AGP/PCI at 66/33 instead of AUTO.
Disable command per clock in Advanced Settings.
Set Vcore to 1.7 V. (good cooling recommended, though. remember to check temps.)
Set Vdimm to 2.8 V.

Doing all of the above should provide you a basis for more overclocking. This is assuming that your RAM can take the 3:2 ratio (yeah, it is DDR400, but that doesn't mean it likes async.). Gradually increase your FSB until you can't post. Once you have hit that wall, lower the FSB by 10 or so and then try to go into windows. Do some prime95 tests. Then gradually increase FSB to a point at which p95 fails in windows.

This is just my way. definitely not the best way. there are tons of experts here who will give you better advice.

The last two settings under gat are not acctually for the GAT mode they are just more memory tweaking options. However, you need to disable them if you want to OC to a decent level. If you have those enabled or the GAT to anything other than AUTO, that is why CPUZ shows faster timings.


My board at 275 is my IC7-G. I went through several sets of Dual DDR before I found one that was able to run good 1:1 and 5:4 I settled on the OCZ PC3700 Gold.

I would highly discurage going above 1.65V VCore. It might just be me but increasing the transitor voltage by as much as .2 is quite high. I think you should first look and see what your CPU is detected at since the D1 steppings have a range they are detected. I have 2 2.4C and all come up in the BIOS from 1.5 - 1.55. I have found that you hit a FSB wall with these new P4C at the default Vcore but really can't get much higher increasing it.

 

[satorn]

porkbun,

Thanks for your step by step guide. That's exactly the kind of help I needed and I appreciate it. I see you have the same ram as I do and you were able to get your cpu to clock at 3.6! WOW!!!!

Yes, I use 3:2 timing to get my cpu to 3.0ghz. But my on board audio stopped working at that speed. I will try out your suggestion tomorrow after work. Again thanks a lot!

 

[satorn]

orion,

Thanks for the warning; I will be careful since I am using stock cooling. I'm thinking about getting the Zalman but I'd like to know if it's much louder than stock fan - my ears still ringing from the Vantek Tornado. heheh

Anyway, is my system score decent or should it be higher? I really am curious about this. How much faster will my system be with a cerrent gen vid card?

Thanks

 

[computer]

Porkbun, what is your "case" exactly, is that it....what you wrote? I was about to get that exact memory!

Gahh, Porkbun & Satorn, see what I posted before about optimal settings for the IS7x from the Anandtech article.....this link is for the IS7-G, see the IS7 page as well, but I think it's the same text. Scroll down to the paragraph: "Just like the IS7......".

I'll also post this again from OCZ memory, this is from a few different emails:

Hi,
The IS7 motherboard has some issues when you run CPU frequency
and memory frequency in async mode. Other than that, you can use our
PC3200, PC3500 and PC3700 memory without any problems. If you have any
other questions, please feel free to let us know. We are happy to
answer any of your questions concerning our memory products.

Hi,
It happens to both IS7 and IS7-G. It's board level problem so
it's not just OCZ memory has this problem. Other memory fails to work
in async mode at more than 250 FSB on this board either. If you have
any other questions, please feel free to contact us. We are happy to
answer any of your questions concerning our memory products.

Hi,
As far as I know, IS7 and IC7 from abit have this problem. The
MSI 865 motherboard has problem setting memory frequency correctly with
CPU/DRAM dividers. You probably can only run at sync mode too. However,
it provides high CPU and DRAM voltage for overclockers. For the
GA-8KNXP motherboard, the highest FSB it could reach is 210 MHz with the
current BIOS release. P4C800 and P4P800 should work fine in async mode.
But the problem is these two boards are that you can only run at CAS 2.5
with PC3500 modules. Right now, every Intel 875 or 865 motherboard seems
to have minor problems here and there. I guess you can only select a
particular board to serve your purpose, either sync or async. If you
have any other question, please feel free to ask us.

 

[porkbun]

Yes, I use 3:2 timing to get my cpu to 3.0ghz. But my on board audio stopped working at that speed. I will try out your suggestion tomorrow after work. Again thanks a lot!

That is most likely due to your overclocked PCI bus.

 

[computer]

Orion I was also looking at that exact same memory. I have not been able to find it. Where did you get it please? The first two hits for it at pricewatch (2x256) are either a bad link or NOS of course, and the next place is $11 more @ $230. Wow that stuff is HIGH, ~$65 more than GeIL Ultra Platinum PC4000.

Yes, it is exactly what I wrote. Ignore my signature--that was with old RAM. I am unable to post using 1:1 at 250 MHz except when the 800 MHz strap is used. Keeping the same strap at an FSB of 300 MHz, the 3:2 and the 5:4 ratios do not work--no POST. That's it. That is my case. I read that quote from OCZ many times, but that does not explain why my old GeIL could do 3:2 but not the Ultra Platinum PC4000. Now with the new expensive RAM, there is absolutely no way I can run my CPU at the old 3.6 GHz speed. I am a bit disappointed. I just wanted to share some experience with people here. Remember I am not saying GeIL is bad. I absolutely do not want to get flamed. In fact, I could have kept myself quiet. It is 100% possible that you get different experience using the same RAM.

 

[computer]

That OCZ info was for the person that was using OCZ memory. But also for you I guess since OCZ stated the IS7 can't or has problems running async memory (any brand) which is what yours won't do. That's odd about the GeIL, I'd ask them and see what they say, I certainly would like to know why the old stuff is seemingly better than the old. Please let us know. sales@geilusa.com

I already sent them an e-mail yesterday. I will tell you what they say.

 

[computer]

Thanks.

 

[porkbun]

I need some info quickly. Please help me out!

I need to know if there are modules that would allow me to do the following stably on the IS7:

FSB 300
MEM 240 (5:4)
Strap 800
CPC disabled
everything else auto

My value geil would go into windows under these settings, but the system is unstable. So I think there is stuff that can do this. Sandra benches almost 6400 in bandwidth.

If your stuff can do 300:200 (3:2) but not 5:4, please kindly let me know too. Thanks.

 

[Mav3N]

Well i did it
ordered an IS7-E
1gig of ocz ddr 400 ram
and a p4 2.4ghz c


cant wait to see the results

Hi,

I have an ABIT IS7 and 2 x 256 Corsair 3200LL TWINX Dual Channel RAM. I am currently not overclocking at all, and in the BIOS the soft menu is set to default for my processor, which is a P4 2.8c. I just downloaded the latest version of CPUZ (1.19a), and it now shows you the memory frequency currently running. Now what I am concerned about is that on mine, it shows Frequency 160.4 MHz and FSBRAM at 5:4 This cannot be true can it? I mean it should be running at 1:1 correct, since in my BIOS it is default, and when I boot up, the screen says RAM 200/200, which means it is should be running at 200MHz correct? Is there any other software that would be able to report this information, so I could compare it to CPUZ. Also, if anyone else can, please check their computer using the latest CPUZ, just so we can find out if it is my problem, or with CPUZ reporting it. Thanks.

SuperG03

I have the exact same problem, it goes away if you set GAT to auto, I'm just curious if this is what GAT really does.

Forget what I said. This GeIL PC4000 Ultra Platinum stuff is not working at DDR500 as claimed. Not at any combination of settings. It looked good on the first couple passes in Memtest, but it finally crapped out. 800 MHz strap, 1:1, 250 MHz FSB--NOPE, IT JUST DOES NOT WORK. I will just have to pay the restocking fee, as GeIL is not providing me with any constructive support.

I have 2 sticks of UP 4200 from GEiL and they work fine at 250 DDR Duel channel 1:1 hell i even got them running 2.5-7-3-3 no problem....

Cant seem to get the memory to run at the 533DDR rated spec though, but there can be all kinds of reasons for that. I have a watercooling kit on the way and I will see whats up.

Async is funny too locks up during the memory test... but I dont really care for running it async anyways (the reason for running pc4200 is to run it sync imo)...

I'll have some more fun with the memory tommarrow but I bought it about $60 cheaper than the Comparitive Corsair 3500 and I get the same if not better speeds.

GEiL is not bad but it can be better, wonder what chips the UP 4200 is using?

Good for u, but the PC4000 UP just is not for me. I was planning to run 300:240. It does not happen of course. The fact that it does not even do 300:200 is just ridiculous. GeIL claims this stuff is "optimized for the i865PE/875P chipsets."
