E6400/P5B Deluxe overclocking nightmare Can anyone help

[loki5667]

Had another thread but started a new one with a title that might draw some more help

E6400
P5B Deluxe
SUPER TALENT 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 4-4-3-8
Corsair 620HX
BFG Tech GeForce 7950GT 512MB
74gb Wd Raptor


Having major problems trying to oc this setup. Been trying different settings the past 3-4 days and can't figure out if I am doing something wrong or if there is an issue with my parts. So far I am having no luck at all passing memtest86 when oc'ing.

Any help will be GREATLY appreciated

Set the FSB to 405 and the RAM to 810mhz

Use the recommended voltage for your RAM as well as the advertised timings (nothing else)

Disable C1E, SPEEDSTEP, AND ANYTHING THROTTLE IN BIOS.

Set your CPU Voltage to 1.45V

If it works, try lowering your CPU Voltage until it fails again!

have you ran your memory at stock settings and had it pass memtest? That should def be your first test, if its failing at stock speeds then you need to return your memory.

Didn't work for me. Can't pass memtest but can boot into windows. Noticed that using pc probe the vcore is only showing as 1.4 when I have it set to 1.45 in the bios

At stock settings it easily pass 5 passes of test #5

Use the Intel TAT.

5 passes of test #5 is not enough. I let it run for hours and hours 300-400 passes at the least.

and vcore being lower than what you set in bios is typical of asus boards. it's called a vdroop.

i have a very similar setup to yours except a 6700 and i am running at 8 x 475. keep messing with the settings.

I'll try setting everything to default and then letting memtest run for a few hours to see what happens. I didn't know you had to leave it running for a long time to check if the ram was bad.

Also at this point I have no clue what settings to even try and play with. Even trying a FSB of 275-280 the system will bomb on memtest. That was the main reason I've been asking for some help because I feel like I'm doing something really wrong to cause it to bomb non stop.

 

[Shimmishim]

have you manually set the timings or is it all on auto?

and yes, memtesting involves running it for hours, not minutes.

usually an error cn show up quickly but sometimes errors won't show up for hours so its best to loop test #5 for as long as possible. Some people go upwards into 1000 loops just make sure (eva2000)

 

[Rafael]

Well I got a pretty similar system to yours. Except for the VGA, HD and PSU.
Did you set manually in the BIOS the ram spec?
vdimm 2.2v, 4-4-3-8 and 800 Mhz.
Try to set that and leave the memory ratio in auto.
So the ram will run in the specs and the CPU will run at default clock.
Give that a try.

[loki5667]

Yes the mem timings are set to 4-4-3-8-6-42 and I left the rest at 10. I had the vdimm at 2.25 since there isn't a choice for 2.2.

I had been starting off at fsb266 and mem at ddr533 then uping the fsb from there. I will try setting the mem to auto and see what that will do for me

 

[Shimmishim]

okay give that a try.

most likely it'll set the auto timings to 4-4-4 or 5-5-5

also, why don't you try fsb 266 and the 2:3 divider to give your mem a boost to ddr2-800 (rated speed).

You mean leaving the fsb at 266 and then setting the mem to 800mhz? I've done that with the mem timings listed on the ram and have been able to pass test #5 past 5 passes without any errors. It's once I start trying to raise the fsb that I end up having issues.

I'll try what you've recommended later tonight and post up what kind of results I get


Thanks for the help

 

[Shimmishim]

also try goign straight to 400 ... i.e. 8 x 400 and see if that works.

its strange it won't work underclocked (the mem that is) but works fine at rated speeds...

if 8 x 400 is too much, try 7 x 400

 

[loki5667]

I think what I typed out didn't make sense.

If I leave the fsb at 266, set the ram timings to the rated speeds for the ram, it WILL pass the test for 5 passes (though from a previous post I now know I need to let that run even longer). Once I start raising the fsb from that point is where I run into the errors.

I also had tried jumping straight to 400 and then tried 401 and 405 since someone had said that sometimes 400 won't work but just above it will. Doing that I was either starting out at 266/533 or 266/800 and raising the fsb. When doing that I can't complete 1 pass of test #5 without errors. The number of errors ranges anywhere from a number in the 400's to as high as in the 2000 range using different settings

^man I hope that made some sense

 

[Roguestar]

Have you bumped up your northbridge and FSB voltages by 0.1v? Set your PCI-Express frequency to 100Mhz.

 

[loki5667]

This is what I have been using for the most part. I have tried different voltages each time I try to run a new fsb

Ram timings I have used the default for my ram (4-4-3-8) and also tried 5-5-5-12 and 5-5-5-15

all your settings look good to me.

Try it @ 7x300 (DDR2-600) with same settings also if that doesn't work.

 

[loki5667]

n7- I used the settings you listed and the 401/802 setting didn't pass. Changing the multiplier to 7 and fsb to 300 passed. But isnt that actually underclocking the chip?

 

[loki5667]

These settings work if I set all the voltages to Auto. Is there a way I can see what it's setting them to?

Hmm...

What do you mean by all voltages?

All the motherboard voltages, or are you setting RAM & CPU voltage to auto too?

It seems to be that your P5B-D needs extra voltage (not sure which aspect yet though) to allow stable 1:1 overclocking, which somewhat explains why auto works well, as it supplies what it thinks it needs then.

That all being said, while Memtest is fun & well, i really don't care about it too much, since it's not an OS environment application.

Have you run Orthos blend?

If that runs fine for a couple hours, & you can play all the games you want w/o issues, i'd seriously not worry much about Memtest.

The whole list of voltages set to auto

I'm just worried if auto would set things too high.

 

[Shimmishim]

no, auto will actually set it low.

Err, i don't think so...

Auto increases as overclocking is increased AFAIK, so unless you've measured with a multimeter, i doubt that's correct, aside from maybe certain cases.

While i personally haven't messed with auto, i recall comments from people asking with their voltage was reading so high when they were using auto.
