So my prob is, my CPU could handle a little more on the FSB, but then my ram crashes. If I drop my divider, I can raise my CPU up a few notches (3.35GHz) but then my ram is under 1000mhz.

What do you think would be better... 200mhz more on ram, sacrificing 45mhz on the CPU? Or more CPU?

I assume the former.

I can't even do 410x8, which pisses me off.

EDIT: My FSB is +.1v, my MCH is +.2v my DDR2 is +.5v (.1v over the OCZ warranty limit, .2v over their specs)

Bump up the FSB to +.2v and see how that goes.

The DS3L has some RAM Vdrop. At +.4v, I get 2.06v for the RAM. HWmonitor tells you what the RAM voltage is.

When you run memtest, it's supposed to be ran like Prime. You need to run memtest (let the test loop) for a few hours. It's like the Prime 95 for RAM. It might pass an hour of memtest or 10 tests fine, but it can fail on the 11th test or 5 minutes later after passing it for an hour.

Loop test 5 on memtest. IIRC, it was the best way to check for RAM errors. Loop test 5 around 10-15 times, then loop the entire memtest 15-20 times. That method won't check for 100% stability, but for only 15-20 passes, it'll tell you if you have any problems with the RAM. If you want full stability, you'll have to let the test run a lot longer such as 12 hours or 20 hours, etc.

The 370x9 and RAM at 1100Mhz would seem best. 45Mhz on CPU isn't much since it's already around 3Ghz. The 200Mhz on the RAM would probably have more impact on performance.

Sounds like it's not getting enough juice. Bump up the Vcore some more. If that doesn't work, throw on a bit more NB and FSB voltage to see if that helps.

Those are some pretty high idle temps.

I also see that Everest says your RAM is at 2.02v. Bump it up to 2.1v-2.2v. The DS3L has some RAM voltage problems.

My ram voltage is 2.26 in CPU-Z. Only a .04 drop on the ram voltage. I have already bumped my FSB up to +.2v. Didn't seem to do much. When I run memtest, I loop test 5 for 3-4 times, and then run 1-6. Then I usually run blend for awhile just to make sure.

Once I get that passed, then I'll run it over night.

Right now I am trying 420x8, divider @ 2.5

So far so good. Not as high as I would like it though. My ram can handle more mhz, but I can't even post when my FSB is over ~425. But I don't think my CPU will handle 420x8

i put the ddr at +.4 and this is what i am at now.....and also the cpu is still @ 479x7 and i put the cpu power at 1.400 but you can see how much it dropped

You can try +.3v on the NB and FSB. Beyond that, I don't know what could be the problem. You might have a FSB hole or a bad chip. If +.3v for NB and FSB doesn't work, then voltage isn't the problem.

Your RAM at 2.26v is good, although a little bit high. Up to 2.2v is the safety limit for DDR2 RAM. That's why so many companies void their warranty if people exceed 2.2v, IIRC.

That's normal. If you want to lessen the amount of voltage that drops, do the mod in my sig.

If you bump up the Vcore from 1.3 to 1.4 and up the FSB and NB to +.2v (or +.1v more than what it's at currently), you should be able to achieve an OC beyond 479x7 (ex: 485x7). If you push the chip anymore and it's not stable, then it's definitely not a voltage problem.

Your 4x1 RAM and high FSB might be straining the NB a bit, or you're bottle necked by your RAM. Throw in a cheap 2x1 kit rated for 1066Mhz if you can to see if RAM is bottle necking you.

Well, my VID is 1.3250v which from what I have read is the worst of the G0. About the same as a B3. Anandtech even did a review, which can be read here.

So, I have about the worst chip that can still be called a G0.

I ran blend all night and had no problems with 356x9 with a 2.5 multiplier on my RAM. That only gives me 3.2GHz on the CPU and 890MHz on the RAM. But, it is a decent overclock and I doubt I am going to notice anything that spectacular by going to 3.35GHz and 1000MHz.

Stop me if I'm wrong.

I am going to lap my HS and IHS tomorrow and then pencil mod. We'll see if that gets me anywhere.

Thanks for your help Rpg2. I appreciate it.

is there a way to change mem timing in the bios im tring to try a setup someone told me the timings are 6-6-6-18-60

Hold control+F1 at the main bios screen, and then go to your voltage page.

6-6-6-18 is kind of loose. I would try 5-5-5-15.

neither worked , can't get pass 481 without it crashing, this is with only one kit of 2gb also...i took the other out to see if it took heat off the NB

Are you stable on AUTO? If so, what does CPU-Z say your timings are on auto?
