GA-P35-DS3L OC Time!

[thenewguy001]

Thanks.

I'm planning on doing 333x9 (3GHz). I've read that some memory ratios are less efficient, and that you should be doing a 1:1 for intel cpus. Since I have DDR2-1066 I have quite a lot of room for OCing from the default 266MHz bus of the Q6600.

My default right now is 1:2 (BUS 266x9), (Ram-533, DDR2 1066)

I'm guessing it's still better to use a 5:8 ratio for 1066MHz ram than a 1:1 ratio for 667Mhz ram. Is this correct? What would give me the best performance? It's a gaming rig and I want fast load times and minimized stuttering.

I also have a question regarding gigabyte boards' memory multiplier vs memory ratio in OCing guides. I'm mathematically challenged and can't figure out the relationship between the two. What translates to a 1:1 ratio, 2:1, etc?

Antec 900 has 3 120 mm and a 200 mm exhaust fans. I added another 120 mm on the side and another 120 mm in the harddrive casing. All blower only 200 mm exhaust. So a total of 6 fans. Plus the psu fan.

Hey All.

I have a issue with my mobo. GA-P35-DS3L with e2180 and i can't oc.

I tried to change "CPU Host Clock Control" to Enabled, without even changing FSB(default 200) and save. On next boot i get to flash screen and then it restarts again with changed CPU Host Clock Control back to Disabled.
Maybe is this a memory problem.
I got: Geil 2GB (2 x 1GB) 800MHz DDR2 and also OCZ Platinum 1GB DDR2-800 CL 4-4-4-15 ATI.

Any1 else same issue? Or any help whoul'd be appreciated.

Thanx.

What's your memory voltage? Try increasing the memory voltage to +.2 .

I had a similar problem with mine last week. I had 2x1gb Crucial Ballistix PC2-8500 in at with the bios ddr2 1.8 setting on +4. All was running fine until one morning last week I noticed the bios boot screen displaying the ram as 833mhz instead of 1066, and my cpu speed as 2.66ghz instead of 3.4.

I went into the bios and noticed that the memory was being shown as DDR2 800 while the cpu was still 3.4ghz. Booted into windows and cpu was indeed at stock 2.66ghz. I thought the memory voltage might be the culprit because at +.4 instead of 2.2v I was seeing only 2.064v. Swapped the ram to some Buffalo Firestix I had and the problem went away. My ddr2 1.8 setting is now set to +.3 and 2.03v.

The vdroop on this board seems to be a problem and you need to set the volts a little higher to compensate.

do you guys need any extra voltage on the MCH for 445fsb? I'm trying to pinpoint which component needs more voltage. On a side note: is the vDimm drop really high or what? I have to set the RAM voltage to +0.7v (MAX) just to get 2.22/2.24 (idle/load).

Depends what is your CPU - with a Dual Core, +.1V; with a Quad, +.2V. As for your side note, I don't remember having such a Vdimm droop has severe as yours - Vcore droop yes though. Using many different sets of sticks, I never had the necessity to add more than +.5V to the Ram for stability.

What's your setup and speeds?

And welcome to the forums.

Here's my Rig :

GA-P35-DS3L /w Thermalright HR-05 on the NB
e8400 /w Thermalright Ultra-120 eXtreme
2GB OCZ Platinum Rev.2 PC2-6400
BFG GeForce 7600GT OC

I was initially trying for 8x500. But my ram couldn't break 948Mhz with 5-5-5-15 timings /w +0.7 (in bios).

I'm using CPUID's Hardware Monitor and speedfan to determine the ram voltage. Both programs give me 1.9-2.4v. The weird thing is that the vDIMM starts off at 1.9v under load. Then slowly (after an hour of orthos blend) climbs to 2.2v load.

So considering my ram situation, i've decided to go for 9x445 instead. Putting my ram @ 900Mhz 5-5-5-15 (can't do 4-4-4-15 no matter how much volts i put in).

Another question. Is there any vDroop mod or any way to combat it? I've tried enabling C1E and ESIT but it doesn't seem to drop my vcore when idle. My multi drops but vcore increases when idle.

Thanks for the reply 3.0charlie. Hardware canucks looks like great community to be a part of.

500 FSB on the DS3L is something not easy to accomplish. Follow what Prof.Doc Silver did in this thread to pass 500 FSB. I can't since I'm using a Quad on my board (see sig).

The board has 1.8V as the Vdimm default and I don't recall seeing a Vdroop mod for it - simply raise the Vcore.

You need to set C1E/EIST on, and for CPU voltage you have to have 'standard.' If you set some number that sets the idle volts higher than the load volts! It's kind of weird. I don't get it myself as to why this happens.

Other than using a bit more power, it doesn't contribute to heat (idle). I still don't get it. It's another reason i'm trying to oc by keeping with stock volts.
