Stuck while trying to OC a Q6600 on a Gigabyte MB - advice requested

post #1 of 8
Thread Starter 
This is my first time trying to do a major overclock, and the Gigabyte BIOS is driving me nuts. First, the basics:

CPU Q6600 G0 SLACR (lapped)
MB: Gigabyte GA-X48-DQ6 (unfortunately, it's so new that its hard to find info on)
cooler: Xigmatek HDT-S1283 (also lapped)
PSU: PC Power and Cooling S75Qb 750W
video: Zotac GeForce 8800GT 512 MB
ram: G.Skill 4 GB (2x2gb) DDR2 1066 (mfr. specified voltage is 2.1, with 5-5-5-15 timings, when the motherboard is set to autodetect timings, it gets 5-7-7-20, right now I have it dialed in to the recommended 5-5-5-15)
fans: 5x Thermaltake A2016 80mm variable case fan

I'd like to overclock the chip to 3.6 GHz (from 2.4) by raising the voltage to about 1.48 and the FSB to 400. When I do this, the computer posts and boots, but as soon as a start a Prime95 stress test, the computer restarts in a couple seconds.

I *think* the problem is in my RAM settings. Apparently the RAM settings on the Gigabyte bios are somehow tied into the FSB settings, but I don't understand how. (i.e. changing my FSB to 400 does strange things to my RAM, such as making it run at 1200 rather than 1066, etc)

My question is this:
What should I set my RAM System Memory Multiplier (SPD) to in the BIOS when I overclock the Q6600 to 3.6 (400 FSB)? What about with the processor at 3.4 (If 3.6 will not work with my components - although I REALLY hope it will)

The SPD menu (used to set RAM frequency) is set as follows (and only contains these choices):
Auto, 2.00A, 2.50A, 3.00A, 4.00A, 2.00D, 2.66D, 2.00B, 2.40B, 3.20B, 2.66C, 3.33C, 4.00C

The explanation for this menu reads as follows:
Auto -> Set memory frequency by DRAM SPD data
(G)MCH strapping: x.xxA -> FSB 266 MHz; x.xxB -> FSB 333 MHz; x.xxC -> FSB 200 MHz; x.xxD -> FSB 400 MHz

Should I run this RAM lower? Higher? Get different RAM? Will it help to underclock the RAM? How? I don't understand how to 'fix' the RAM problem when I OC the CPU.

Quick summary: What SPD memory setting should I use with 1066 RAM when overclocking a Q6600 to 3.6 GHz (400 FSB)? What about 3.4 GHz? (378 FSB I assume)

Thanks for the help! (and tell me if I need to post anything else)

Also, if anyone has experience with this motherboard/general cooling setup, is 3.6 GHz stable a reasonable goal? Or is that only likely if I get a reallly lucky set of parts? Anything else I should try?

read the intel overclocking guide: the part about the memory being integrated in with OCing...

I read it, but am not sure it addresses my issue. Is it saying that as long as my RAM frequency is at or below 1066 MHz I should be okay no matter what SPD I choose?

I would try running the ram at 2.00 (1:1), which would yield 800mhz. It's slower than what the ram is rated for but that should eliminate the ram as a possible factor in not achieving a stable 3.6ghz. Once you get a stable o/c then try to mess with the ram and try a different multi. Once you switch the setting from auto to something else it should tell you the speed that you will be running the ram at. I'm not sure about your board but thats how my gigabyte board is.

You probably need to add some volts to the FSB and MCH as well. If you have never done a lot of overclocking I think that trying to jump straight into 3.6ghz might be a little too much. There are more variables than just vcore and when trying to reach the higher clocks, those things come into play more.

You should also go into the UserCp and fill out the specs on your system.

Got the same problem with both 2.00 and 2.66, so I looked at the system more, and now it seems I have a much more worrying issue.

The VID of my chip (according to Core Temp, nonoverclocked) is 1.3000v
The cores run at about 40C nonoverclocked. (for some reason, 0 and 3 seem to be running much hotter than 1 and 2 (34 vs 39))

Here's where I started panicking:
Even without overclocking, using motherboard defaults, as soon as I start Prime95 the core temps jump from 35-39C to 73C and keep climbing (I stopped it then). That CAN'T be good!

Any ideas on what's going wrong? Maybe I put too little thermal paste on? Or too much? I though the idea was to put on as thin a layer as possible, especially with lapped parts?

Panicking now,

wait, you lapped the cooler? you realize that means you lapped the heatpipes? thats not good, could be the cause of temps, may have damaged the heatpipes

without overclocking that temp seems too high. Maybe try to re-seat the hsf. It's normal for quads to have different temps. Mine has different temps at idle but at load they are all the same. I used to have different temps until I lapped it. I always think I put too much thermal paste, I just put a small dot right in the middle and thats it. I tried the line and the dot and I like the dot better, either way it's going to spread.

Honestly though, I would try to work my way up to 3.6ghz rather than just jumping straight to it. Some people have a lot of experience with certain items and they can make pretty good guesses at what they need to adjust. Another thing that you have to take into account is that every chip is going to be different and some need a lot more vcore than others. Some might never hit 3.6ghz while other can reach 3.8hz. I would take it a bit slower and make adjustments accordingly.

I have to raise mch to +3 just to boot at 3.6ghz while other people with the same set up can do it with just +1.

Even if what you are trying to do worked I think it takes away from some of the fun and the learning experience. I'm no expert but I have learned a lot from just trying different things and moving up slowly. The guides gave me a good idea of what I need to do, then I put it to use on my set up.

First of all, your VID does not change. It is factory set.

Now, what Vcore are you running your quad at stock? I don't recommend leaving on Auto. Look at your VID, and set the Vcore to that amount for stock.

Then run prime95 for your load temps.

Also, memory ratio works like this.

If you are running say 400fsb, on a 2.00 memory ratio = memory running 400 x2= ddr2 800 speed.

If you are running say 400fsb, on a 2.66 memory ratio = memory running 400 x 2.66=~1066...



Have you turn off all the EIST, thermal control things in the bios?
