I think i might have hit a wall in overclocking!

Doh!, you did say that in your 1st post too 😱

So have you tried boosting the MCH voltage?

Fair enough 🙂.I take it you tried upping the MCH voltage in small steps?

I wonder if your NB was getting too hot?

I've been playing around with my mbrd recently (Asus P5Q Pro), I lowered the multiplier on my Q6600 to x8 & cranked up the FSB. Eventually I got it upto 419 MHz FSB (so that my CPU was back to 3.35 GHz), however I couldn't get it stable (as in 24hrs OCCT) at that FSB with timings & max MCH voltage I'd chosen. With NBv(MCH) at 1.16v it crashed OCCT in 1min, @ 1.18v it crashed OCCT in 7+hrs, but at 1.2v it crashed in 4hrs 45mins 😛, I assumed the NB was getting too hot, but that is a guess. Anyway I dropped the NBv to 1.18v & the FSB down 2MHz & it's just passed a 24hr OCCT test 🙂.

My NB has a pretty big HS on it, and it wasn't really warm to the touch. Yeah i tried each voltage individually. The only one that worked was either 1.0 or 1.1. Anything else and my system hangs.

I've got to say boo on the overclock i achieved versus potential, but a A-ok in terms of performance.

hi all. I found this thread when browsing google and thought I could help. I have the same MOBO and CPU and I also went through lots of anguish when I tried to OC the q8200 but I have some good news to those who have the DS3L MOBO + qQ8200 CPU: I found the rock solid values for 3Ghz. they were tested with prime95, intel burnin test, PCmark and 3dmark06. I had these settings rock solid while folding with the GPU and CPU 24/7 (100% load on all 4 cores and the video card) for the past month (its been on folding full blast since)

so here are the exact values in bios:

FSB: 429Mhz

PCI-E: 100Mhz

C.I.A: DISABLED

ADVANCED CLOCK CONTROL: 800mv
800mv
ops
0ps

SYSTEM MEMORY MULTIPLIER (SPD): 2.00B

MEM: 858Mhz

RAM TIMINGS: 5-5-5-15

ADVANCED RAM TIMING CONTROL: ALL AUTO EXCEPT tRFC IS 48 (DEF. 72)

CPU Vcore: 1.31250V (1.264 in CPU-Z because of V-drop)

CPU TERMINATION: 1.200V

CPU PLL: 1.650V

CPU REFERENCE: 0.762V

MCH CORE: 1.300V

MCH REFERENCE: 0.760V

ICH I/O: 1.550V

DRAM: 2.2V

ADVANCED BIOS FEATURES:

LIMIT CPUID MAX TO 3: DISABLED

NO EXECUTE MEM PROTECT: ENABLED

CPU ENHANCED HALT (C1E): DISABLED

CPU EIST FUNCTION: DISABLED

all the other values were untouched.
my RAM is different from yours, so the only thing that would make these settings not work with your setup if your RAM can't OC to 858Mhz. these settings underclock my RAM from 1066 but they allow for the 1:1 FSB😀RAM ratio.
the reason I was googleing this topic is because I know this chip can get to about 3.5Ghz and was looking for clues on what to adjust in BIOS to achieve that.

it seems your PSU is powerful enough to support this OC. the only question is the RAM but I think that should be OK too. good luck with your OC.

Wow, thanks man. Im going to go home after my finals and try that out. When i ifirst overclocked i didn't mess with my ram so it was at 425+ so i might be good.

Welcome to the forums!

 

[TurtleCrusher]

One quick question, if my ram cant handle those speeds at CL5, if i were to loosen my timings would that relieve stress on the memory?

 

[cubeless]

you may need more voltage on the chip... but go 6-6-6-18-24 on the mem and see... i got my q8200 @ 450fsb right now on an evga 750i ftw... using ocz platinum 1066 @ 5-5-5-15-20 and 1.30 chip voltage... doesn't seem to want to go any higher even with more juice...

sometimes they just don't want to give it up easy...

 

[nyker96]

pretty sure this is either a m.b. fsb problem or the ram needs bit more juice to go higher.

 

[TurtleCrusher]

I just used that settings and it wouldn't load the windows bars. I was at 1.8V on my memory. I upped it to 1.92V or 1.94V (I'm currently at FSB 410) and i'm in windows now. I'm not sure how stable it is.

This is my RAM right here

http://www.newegg.com/Product/...x?Item=N82E16820220227

How much juice will it need? I'm going for stability and not speed running.

 

[TurtleCrusher]

Well I used those setting but my memory at 2.06V and it was stable at FSB 417 (2917mhz). Anything higher it wouldn't pass Linx. I upped my voltage to 2.1V and i had numerous different types of crashes.

I reverted back to my stable overclock of (393x7) 2750mhz at 1.14V. At the highest stable overclock with my voltage at 1.3V i had temps at 70. I'm running linx (i'm on my EeePC typic this) on my main rig and the temps aren't hitting 60. I'm keeping it here. Thanks for your help though.

 

[cubeless]

the memory is rated at 2v!!! if going to 2.1 'caused other crashes' then something's really wrong...

and 70c isn't too hot for that chip... but unless you get > 200mhz with more twiddling then it's not worth the grief...

I took it to 3ghz when i went to 2.1V and above and it didn't seem to like that at all. I had crashes that "looked" like video artifacting to blue screens. Do i really need to push it to 2.2V if i already have these problems?

Maybe i really did hit a wall. I raised my CPU voltage to 1.25, 1.28, 1.30, 1.31, 1.33, 1.35 and every time it froze going into windows at 400x7 2800mhz.

I guess 2.73ghz is really where my chips stands 🙁

No. Mess around more with FSB V and NB and SB volts.

I thought the same thing when my Q6600 wouldnt post or even run windows for shit at anything over 3 ghz, then I found out I wasn't doing anything to FSB and Nb and SB, once i upped the volt son those I was able to go higher. Im at 3.4 now, waiting for my water cooling stuff to get here tomorrow and see if i can go further.

 

[sbohdan]

check if you adjusted ALL settings exactly as I posted. try losen the timings (see in CPU-Z what are the SPD options and keep the RAM @1.9 -2.0V

the above settings are rock solid guaranteed, so if something is wrong than it has to be the RAM
