4800LA + Venice 0515, strange issue!

[higherøx]

Hi :)

Well, look at my config in my sign.
The problem is that I can't stabilize my memory in SuperPi 1Mb, 32Mb and Prime95 at the same time.

Look: (all the tests have been made with DDR600 2.5 4-3-6 1T [always the same config])

2.7v + 3.3v = 2.77v

SuperPI 1Mb "RealTime" (many consecutive tests): stable
SuperPI 32Mb "RealTime": stable
Prime95 Blend: NOT stable

2.8v + 5v = 2.83v

SuperPI 1Mb "RealTime" (many consecutive tests): NOT stable
SuperPI 32Mb "RealTime": stable
Prime95 Blend: stable

I don't know what more I could do.
My processor is stable at 2.7GHz (300×9) and 1.47v, tested by OCCT, SuperPI and Prime95 Small FFTs for HOURS.

Which config would you use on your day-to-day?
Do you have any idea to solve this issue?

Bios that I tried: 310P, 414-3, 414-2, 414-1, 510-3, 510-2, 510-1, 618-3 and 618-2 (618-2 is better)

Help :)

[pancake]

what have you get your ldt bus and htt volts set to have you tried 2.5-4-3-7 on the mem

[higherøx]

LDT = 300, 1.2v
Chipset = 1.5v

Yes, I tried 2.5 4-3-7 (didn't solve)

Thanks very much.


PS.: The error occurs only in the 5th-6th run of the SuperPI 1Mb "Real Time"

[pancake]

try upping them a bit i ran 1.7 on chipset and 1.4 on ldt

But is it safe to use daily?

I live in Brazil, ambient temps here are at about... 35ºC :D

Thanks

what are you cooling the cpu with??

[ozzimark]

put a fan on the ram :D

[higherøx]

Zalman CNPS7000A-Cu

about 43~44ºC full load

put a fan on the ram :D

It wouldn't be a bad idea, but the problem is that I would lose the good appearance of my case :D :D :D :D :D :D


Thanks :D

change ram 4800la is not good 300mhz is on 2t

This same kit worked at 300 2.5 4-3-6 1T 2.73v with my old venice.

The problem is the cpu memory controller + this memory.

Thanks

I have similar problems with my tccd and my venice 515 3000+(fpdw).

I think that the memory controller isn´t good enought for work 1:1 with tccd.

Sorry for my bad english

[gigi77]

thanks for reply!

Woah hold on. Are you using the 4v jumper on the board (DFI Ultra-D)?

No, of course :D. I don't need more than 3.2v for TCCD.

Thanks

Some Venices 515 have poor mem controlers, but are very good clockers.
I think that this cpu should work better with utt.

But there aren't any solutions? :(

[pcadiction]

I haven´t found any solution. I have my cpu @ 9*303 with 166 divider (and timings 2-3-3-6)
