Switched sticks around and got better OC...

[prodigy_]

Yesterday Memtest+ showed me about 20-21 errors per pass (test 5) at 237 Mhz.

 

Now I've done 40 passes of test 5 already w/o any errors.

 

The only thing that changed is that I (accidentally) switched sticks around.

 

But they're still in orange slots. I'm using the same BIOS 623-3.

(VDimm=3.2V, HTT 290x9 and I didn't touch DRAM settings at all).

And ambient temps are higher today.

Is this possible at all? What do you think?

BH-5.. could have been because of the burn-in and not the different slots. Intresting theory tho

Actually yes I'm gonna make some burn-in with these sticks later tomorrow. But yesterday it was only like 2 hours which is IMHO not enough for such improvement. (Ppl on our local forums suggested 24 hours at least...)

That's something awesome. Now doing 245 Mhz (HTT 300x9, 166 divider) at 3.2V. Still no errors.

 

Don't know what to think about it...

Its a common thing and actually recommended by OCZ when troubleshooting. Good change same goes for your ram.

Yep thats right. I find my old OCZ PC3500EL BH-5 works best if i have each stick in its own specific slot.

Mine are Kingston's but still this seems to work. 5 hours - 400 passes - 0 errors.

Previously they gave me thousands of errors @245 and some errors even @233.

 

I'll test with Prime95/Blend now to be absolutely sure...

[Edit - update]

245 Mhz seems to be the highest memtest stable clock. Prime/Blend fails very soon (Prime/LargeFFTs doesn't so that's certainly memory related).

@241 - Prime/Blend stable.

@247 - 2-4 errors in Memtest+ per pass of test 5.

 

I'll flash some -2 BIOS and try yellow slots.
