Gigabyte GA-P35C-DS3R question / BIOS problems

themask70 · 1 Jul 2007 at 22:07

Hi everyone.

My current system is

Intel E6600 @ 2.4ghz
2gb of ballistix pc6400 ram
GA-P35C-DS3R motherboard
8800 GTS 320MB

I had the system at stock volts and overclocked to 3.2ghz with the ram still at stock timings.
The system ran orthos for over an hour with out issue and played a variety of games with out a problem.

On day 2 the system played up causing me to have to reset the CMOS to get the pc to boot.

Because the board is so new I cannot seemed to find much info for BIOS setting settings and such like.

System is even having issues posting with the chip at 3ghz with stock volts. (hoping I haven't got a bad weak chip)

I know I will have to up volts etc to get stability but I wondered if someone can tell me the BIOS settings for the cpu ie vanderpool tech etc or supply some bios screen shots for maximum overclocking sucesss. Any other suggestions would be most appriciated.

Regards,

I have almost the same set up as you and it was my first time overclocking when I got it, I used a these two guides as the bios seems to be the same and it all worked really well

Cheers, that first one look just like what I need.

Out of interest, what do you have your processor running at?

I had it stable at 3.5ghz with a 500mhz fsb but that needed 1.4625v on the processor which was a little high for me even though the temperatures were fine. At the moment I have it at 3.2ghz with 400fsb at stock voltage and 1.8v on the memory as that is easily fast enough for me.

Ok, cheers. I think part of my problem was that I hadn't given my RAM enough voltage and that was probably why it didn't want to even post.

I have a similar system to you, but using crucial 5300C3. I am running at 3200, but it ran at 3400 fine, it just seemed safer to leave it at 3200. I initially left all voltages to auto, but noticed using Everest that the voltage was high on the CPU for me, it was 1.42. I found that I needed to set the CPU at 1.41250 in the bios to get 1.32/1.36 showing in Everest, checked with CPUZ. At this setting it will run at 3200 all day really cool, (I am using a Thermaltake 120 Ultra). I know the DDR2 should be at 2.2, but I have had it up to 1016 with no problems in auto voltage, which I assume is 1.8v, (am I correct?). I have left the Ram at a multyplier of 2 which according to CPUZ is a ratio of 1:1 which works fine.
I also found the health readings in the bios for the cores reads low, and is reflected in easy tune, so use Everest or something else to check.

Yeah thats the same ram as I have, mine will do 500mhz 4-4-4-12 at 2.2v and will do 400mhz 4-4-4-10 at 1.8v which is fine for my 3200ghz overclock which is the highest my processor will do on stock volts. I havent really seen how far I can push the ram as its fast enough for me as it is and at 1.8v I hope I woulnt have any problems with it and it will last longer than at 2.2v.

I think its best to manually set all the voltages so you know exactly what is going into each component as you dont want it to put too many volts into anything and break it! I could be wrong with this though as I am not very experienced with overclocking so maybe its best to wait for someone with more knowlage to answer.

Cheers everyone, I'll OC it again later.

I think my main problem was that I just didn't have enough voltage going to my RAM and my Processor.

EDIT: Ok, so I tryed Ocing again following the guides I had.

I set the multiplyer to 8

I set the FSB to 400MHz

I set the ratio to 1:1

I didn't do anything to the RAM timings

I set the CPU voltage to 1.4v

I set the FSB voltage to +0.1v

I set the MCP voltage to +0.1v

But... I still keep cold booting, doesn't even post. Any other suggestions or do you think I've got a faulty board?

Bump.

When I did mine I set the ram voltage to +0.4 so its at 2.2v overall.

To try find out if its your fsb or cpu causing the problem you could set the multiplier to 6 so the cpu would be at stock but the fsb would be at 400 and see if it boots, if it does that means your fsb is ok and its your cpu that cant clock that high at that voltage.

Thanks, well after about two hours testing I've found out what the problem is....

It's the memory ratio, the mobo doesn't like it if I change it from 2:3 to anything else, so I'm stuck at 2.7GHz at the moment. But it's all keeping farily stable with the RAM at 4-4-4-10, ran orthos for two hours with no problem and 3dMark and CSS are running fine as well.

But if anyone's still got any suggestions as to how to stop the memory ratio from being stuck at 2:3 then it would be greatly apprciated...
