OC HELP - Any ideas?

[batmang]

i cant seem to figure out my systems problem with oc'ing. currently im at a peak with a big voltage increase. if you look in my sig, you can see what im refering to. my bios is 15, settings listed below, anyone have any suggestions? i just want to hit 250fsb so i can have the 1000fsb / 400ddr going. i dunno why i have to push my vcore so high to sit where im at now. the actual is about 1.63-1.66v. but thats high. i can boot at 3.0ghz with a 5:4 ratio at stock vcore, any higher and it needs higher vcore. SAD. most people get 3.2ghz off stock vcore. Any help would be appreciated, thanks in advance.

Maybe it's your HyperX.

had same problems with geil 3500 utlra plat. doubt its the ram

I don't think it's the ram holding you back. You shouldn't be pushing it running 5:4 ratio, especially if more vcore will help it. I think you just have a cpu that isn't going to oc well. IMO, I would run it at whatever it's stable at with no more than 1.6v and tighten the ram up as much as possible. You may find you get better performance with a slightly slower fsb and 1:1 if you can run tight enough timings.

I would be willing to bet there are more 2.6c's that won't do 3.2ghz than there are that will

 

[batmang]

yeah ur prolly right
its just nice to see " 1000 fsb "

 

[boshuter]

hehe, I know what you mean.... I lucked out and got a 2.6c from Newegg a couple of weeks ago that will do 3.41 w/1.6vcore. I had plenty of "dud's" before I finally got a good one though

 

[batmang]

ive been messing with the 1:1 ratio, currently at 2.9ghz 223fsb / 446ddr / 2-3-3-7 timings (ram default) 2.8vdim, stock vcore. Ive been running prime95 x 2 on it all night, no errors, its really only at 1.47v... so im sure i might be able to squeeze 3.0ghz on 1:1, depending on my ram. we'll see how far i can get.

 

[batmang]

aight, ive reached the highest i can go before having to raise the vcore using a 1:1 ratio. my 2.6c is at 3.0ghz right now using a 231 fsb, stock ram timings at 2-3-3-7, hyer x 3500 433 @ 462ddr. the vcore is at 1.55v but it fluctuates from 1.47v - 1.53v. so the ram wasnt stopping me from ocing, was the voltage. ive kept the vdimm at 2.8v throughout the ocing. i'm hoping i can get a little more out of the ram before having to relax on the timings. we'll see what happens.

1.55v but it fluctuates from 1.47v - 1.53v.

I have IS7-E and IC7 and they are both undervolting. IS7-E was bought new. Similar to yours. Just set it on 1.55 or 1.575 and you'll be OK. This could be also a consequence of a power supply but I do have Enermax 350W and Antec 550W that I used before with no problem. So it might be just the way Abit boards are. I get 3.00GHz with no problem at all, actually fairly easy to 3.2 GHz on both boards. You should be doing that as well. Use 5:4 ratio for bus:memory.
Find the way to cool the ram (fan close by), I get about 2 MHz more on FSB doing this, hard to believe.
Another thing - what kind of fan you have on the chipset?

Off topic : WTH happened? I come back tonight, and nothing but AMD threads all over the place. Thanks for someone needing help with an Intel product.... But yeah, good luck with your OC. It's not like 3Ghz is slow or anything... But keep pushing the limit...

Fan on the chipset? It's the stock cooling fan on the motherboard. Oh, btw, im at 233fsb / 466ddr, 1:1 ratio, 1.575v, actual ranges from 1.50v-1.55v. I'm pretty sure my case setup is a big reason i cant go 3.2ghz stable at a decent voltage. Its a really old case, thats got no fans in it except for the psu fans, cpu fan and mobo fan. Heres some pics..... LINK lol. My case is 6 years old.... didnt have money at the time to upgrade my case, but i plan to get a new case within the next couple months. Maybe when i get it ill try pushnig my cpu some more, but this is the farthest i want to go right now, i dont want to push my voltage any higher. And yeah, WTF is with all the AMD THREADS!

EDIT*- Forgot to mention, the pics you see of my case in the link is exactly how it looks right now. Theres no cover for the case, nothing is screwed in, not even the hard drives. And the floppy drive is still on its side sitting inside the case. Hehe, i need a new case bad!

 

[stevejst]

Two things!
1. First you don't have enough fans there.
2. Your chipset fan is an old version. The new version is like this one. This is much better chipset fan than that funny blue thing they have on older IS7/IC7. If you can replace it. My IS7-E came with the new fan.

For a new case look at this one.
This is a magnificent case, I got aluminum one with the window, it is better than it looks.

I'd recommend carefully removing the NB-HSF, clean off the Pink (gum based) adhesive/TIM, and remove the double-sided sticky shim (prevents any potential airflow down there). Use Automotive sand-paper (wet/dry 400 to 800 grit) and lap the NB-HSF smooth. You'll find the bottom of the Abit NB-HSF's (I've lapped both my IC7-G and IS7-E) are very rough. Considering the surface of the 865-NB the conatct is very-poor. This will increase your performance significantly. You may not see huge FSB increases but the system will run much more stable. Remember that NB chip controls memory through-put, AGP bus, and I beleive it to be as imporatnt as the CPU. After all it will ultimately determine, or inhibit performance effecting over-all system performance. Here's a link to my post at AOA with photo's to show you how I did it. It teakes an hour, and once your done, you'll never install another Motherbords without removing, and lapping the NB-HSF.
Lapping the 875/865 NB-HSF
Don't mean to contradictstevejst but the chipset fan your referring to is only found on the Max boards? Which aren't revisions, but new models. If you were to buy an IC7-G, or IS7-E you'd get the same chipset-fan you currently have.

 

[batmang]

so wait, say i do this, should i apply some artic silver ceramique and put the hsf back on?

I got new IS7-E and came with a new fan. I also have refurbished IC7 and that one has old fan version, just like his.
I cannot really compare the boards since the setup is different but I believe there is some FSB difference. So yes, I would get a new fan from excalibur for $10 shipped, it will increase the FSB and the stability of the board. My IS7-E/2.4C runs perfectly stable (meaning Prime95 torture test) at the soft spot 275:220 (5:4) with this PCMark2002 numbers: 8208/9944/1538 (cpu/mem/hdd).
I can go even higher but I am losing memory timings that way.
My IC7 runs lower on 255 (stable) but with inferior CPU heatsink so I didn't really try to push the clock higher since the CPU temperatures are already close to 50 even without Prime95. So I don't really know what is the difference between new and old NB heatsink but there is one no doubt.
