Experienced OC'r needs help on Q6600. :)

[FR@NK]

Needed 1.52v to get into windows @4GHz and it isnt fully stable.

Only one failed this time 3 mins of running it.. Can i raise my Dram to 2.5? i think that Will do the trick. damnit i wanna exchange the 800 for the 1066 al;ksjdf;lkjsdfl;kjsadf.

heh no imo 2.2v is max for that ram. I would recommend only using 2.1v. That ram is rated at 4-4-4-12 @800Mhz with 2.2v so it should be fine how you got it. If you think its the ram holding you back then drop the multi down to 8 and see if its stable.

Thanks frank SO much. ^^ After 4:20 my core 0 failed on me how much voltage does this guy want lol


Maybe its cause i'm still only at 1.45 -,- haha. i'll UP that Cpu voltage 2moro.. come back we'll get things stable im goin to bed..

I have a bit of Vdroop. I have it set to 1.5, but I am getting 1.47. Yeah, up the CPU volts. Usually you wont need to mess with the MCH or FSB volts until you get past 425 FSB. Memory volts can also cause this kind of problem, but I have my money on CPU volts.

BTW, use this program for checking temps and volts with the Q6600, it is quite accurate http://www.cpuid.com/hwmonitor.php

Make that two! I've set my vCORE to 1.35v in the bios and i see 1.296v @IDLE in CPUZ. Now when it's at full load i'll notice the vCORE dropping all the way down to 1.248v? Does anyone know any settings on this GigaByte board to stop this vDROOP bs? Anyhow this setting is stable 10hr 44min on Quad-Prime @3.2GHz (356x9).

so is 3.6ghz not a lot to expect of a q6600 g0?
I seem to be completely stable up to 2.8ish then past that il start getting restarts (not because i want it to obviously lol) and sometimes it wont even start up correctly, have to restart just to get into bios to change it back.

Would need system specs please....

I had problems to make my Q6600 G0 run stable @3.6GHz on my P35-DS4. No matter how much I increased the vCPU it still wasn't stable. After spending some hours of testing and experimenting I finally found a solution. I had to increase the vMCH for +0.15v and the vDIMM for +0.15v, while the CPU needed 1.35v to be Prime95(I tested 6 hours) stable. It's strange why I need to increase vDIMM, since my RAM is DDR2-1066 CL5 5-5-18 1.8V and I was running it @1000MHz. Now I have set the vDIMM to +0.25 and I am running my RAM @1000MHz CL4 5-5-16.

Ok
q6600 g0... obviously
inno3d 680i mobo
4gb ocz ram 800mhz though its at closer to 960 at the moment to my recollection, not at home
freezer 7 pro cooler
8800gt

anything else you need?

 

[ZenZimZaliben]

For most cases, a q6600 to run as 24/7 machine @ 3.8+ghz you need a good amount of voltage and some heavy duty cooling.

AS you can see from my screen shot to maintain 4.0Ghz I need 1.536Volts and Watercooling to keep it stable. I do not think this would be possible without watercooling so please dont throw 1.5+ volts at your chip if you are on air.

 

[Cowspoo]

haha. okay well i'll stay at 3.6! What do i set my fsb strap to .. idk what that does

 

[dsdavis6]

4ghz?! :-0 obviously i would love to get to something like that, and i do intend to get water cooling eventually.... but shoudnt i be capable of more at stock voltage on air cooling then what im getting?

 

[Cowspoo]

STock voltage.. 1.32v? you'll get a decent 3.0Ghz OC just leave it at that i NEED to leave for school i'll post great settings to change everything to later today a few things are =fsb 333, 2t for ram.

 

[ZenZimZaliben]

3.6Ghz is a nice OC and nothing to be upset about. You probably could hit 3.8Ghz on air...others have...but I am not sure if that is a "24/7" machine. IF it is then they live up north where the ambient temp is probably 10-15 degree's lower. I am betting those same people will not be hitting 3.8ghz in the summer.

 

[dsdavis6]

everyone is talking about 3.4+ and i am getting 2.8 if im lucky lol. Yeah setings would be great

 

[ZenZimZaliben]

Ok here are some setting to try to get to 3.6Ghz

CPU Multi = 8x
FSB = 450
FSB Strap = 266/667 (For ddr2 800 ram, for 1066 266/800)
CPU Voltage = 1.40 - 1.45
FSB Voltage = 1.6
DDR Voltage = 2.1

Keep your timings loose intially. 5-5-5-15

 

[ZenZimZaliben]

Ok that strap will be to high for some DDR2 800 chips. If you don't have a good brand of memory with micron d9's then you will need to lower the strap. 233/667

I say this because if you are running the 266/667 = .398 and @ 250Mhz FSB = RAM 1118, which is too fast. However those settings will work great for DDR2 1066.

one thing... my ddr's recommended voltage is 1.8-2v... is this going to be unsafe? i think my ram is quite poor to be honest for things like this.... also.... this may sound stupid but where do i change fsb strap... i only have the rams speed to change to my memory.... ie 667mhz and i can up it to whatever i want... but not to sure about the 266...? everything else should be fine i think, ie i know how to change and its not above recommended

 

[ZenZimZaliben]

Yes...Always stick with your manufactures voltage range. Regardless of what anyone tells you. Unless youre willing to burn up your ram and void the warranty.

 

[dsdavis6]

ok........ so am i going to have to get some better ram to progress?

 

[ZenZimZaliben]

IF you don't feel safe pushing the ram just keep the FSB/Mem ratio low so you don't kill it. This will not effect how far you can push the cpu.

No, just dont push the ram. Just up the FSB but keep the divider low so you dont go to far over manu specs.

You may want to try a 233/533 strap if offered.

 

[pepsi71ocean]

Try my specs they might help. Google a search ofr CPIUD Hardware Monitor its much morte accurate. Speed fan is off by about 15 degress if is remember right.

I'm in the middle of a FSB hole where i am if i go to 1500, or 1520 i can't run stable, but 1525 seems stable for me. If i go higher, i'll let you know.
FSB 1.4
Spp 1.45
Mcp. 1.52
SPP<>MCP 1.42

ok........ so am i going to have to get some better ram to progress?

No, I'm running 3.4 GHz with the same type of ram you have. 4-4-415-2t is good up to around 435MHz for me. however if you want to go to 1000MHz you should switch to 5-5-5-15-2t @2.2volts

 

[ZenZimZaliben]

Isn't that crazy. Took me a while to figure out that the end of one ratio maybe more unstable the the begining of a higher strap.

 

[dsdavis6]

ok... has anybody had experience with this motherboard. inno3d 680i if you missed it. i think my mobo and ram will hold me back, even if i leave my ram settings the same as they are speeds timings etc. as soon as i try and go anywhere with the cpu... past 2.7-2.8ghz i get unstable.... as in i wont get into windows... or if i change multiplyer i wont even get into the bios properly, i need to restart twice so bios loads in safe mode? i have also noticed limitations in settings, im not seeing a strap setting, unless thats the ratio in which case i only have 1:1 3:2 and another, 5:4 i beilieve. i also think fsb voltage is capped at 1.5 if i remember correctly i will have to check again and make some notes..
thanks for all your help by the way

 

[Cowspoo]

FSB 1.4
Spp 1.45
Mcp. 1.52
SPP<>MCP 1.42

What's Spp and Mcp and mch?

My 6600 was running at 3Ghz on auto, and in windows it was around 1.2 with vdroop. what voltages are you running at, that i can't find

What's Spp and Mcp and mch?

SPP SouthBridge
MCP NorthBridge
SPP<>MCP Is the SouthBridge to north bridge connector.

My spp limit is 1.20 COre three crashes after 4 mins.. the others are fine past 12 mins i quit it then..
CPUv= 1.4875v
