got new vx... something isnt right

[Zeonic_Warrior]

I got a set of 1GB OCZ Gold PC4000VX and a ddr booster last week, and i cant even get my cpu to run at its previous speed now. My question is is it the mobo, ram or cpu?

cpu: 2005 winchester 3000 (ew on 05, i know)
mobo: MSI K8N Neo2 Platinum bios 1.8

I used to have set of DC 1GB OCZ PC3500 Gold and i could do 304x8=2432 with a ram divider of 133 (ram speed 202mhz 2-3-3-7)

My VX will run fine 1:1 with htt at 200, but it wont run with a divider of 133 when htt is 300 (which would give a mem freq of 200). the vx cant do 1:1 at 250htt (even at 250x7 stock cpu volts), BUT it is 100% stable in memtest86 at 250mhz 2-2-2-10 (burned in 40 something hours). this led me to believe that its either my cpu or mobo, and i suspect it is the cpu's integrated memory controller. is there anything im missing here? the reason im asking is that im planning on getting a san diego and i dont want to get it and still not be able to run my vx at ddr500 speeds.

This is a CPU memory controller and board/BIOS issue. The memory does not effect dividers, although a BIOS might allow dividers to work with some RAM and not with others..

I'm not sure if that is the latest BIOS or not. You might try a different BIOS.

Anyone have any ideas?

Conflicting statement there... define "won't do 1:1 @ 250htt" versus "100% stable in memtest86 @ 250"

Also, what test(s) of memtest86? (if you just ran T5, try T8...)

Peace

[Zeonic_Warrior]

isnt stable in windows with 1:1 250htt. did standard test rotation in memtest86 for about 12 hours, test5 for 30 something hours, both at 250htt 1:1. bios 1.8 is the latest official bios

I think the Neo2 can't run divider on VX IIRC

Neo2 + VX PC3200 = no dividers above 27ish.... sorry bro

...many being there and have NOT done that, if you know what I mean...

[Zeonic_Warrior]

i dont think i fully understand how dividers work. right now i am running 261x9 with memory divider at 166, so what is my divider total at? (idk how it could be "27ish") and why can i run at this speed but not even 250x7

The Neo2 is not the best mobo for high voltage ram imo. There are only a few people who have had success with UTT type ram on the Neo2.

My own experience with Twinmos UTT was that it was no good at all on the Neo2 with a booster and only slightly better using the 3.3=Vio mod. On the DFI NF4 the Twinmos was good for 257mhz

[Zeonic_Warrior]

so basically my motherboard says no to the vx... blaaaah, i just upgraded to s939 o well.

This is old BH5 @ 3.2vdimm on the Neo2 board...



I suggest trying bios 1.37beta. It seems to work better with high-vdimm sticks. Dont know about UTT...

Well, I would not say that. Neo2 works great with a DDR Booster and old school BH-5 (all of BH-5 I have do at least 260MHz, one did 276MHz Spi16M stable). Although, I could not get much from it, when I tried touse 2x512MB Mushkin LvL II. With OCZ VX, I got max of 260MHz SPi 16M< stable and 256MHz Prime95 stable.
Dividers with OCZ VX - it's a different story as there seemed to be some sort of incompatibility issue between Neo2 and VX, which prevented use of dividers above certain HTT, 27ish usually.

I have a Neo2Plat as well and I've been looking for months for the best RAM for it. Considering what is currently available on the market, what is the general consensus regarding RAM selection for the Neo2 939pin board? TCCD is expensive and becoming difficult to find.
I am able to run at 300FSB on the board but would have liked to see what 2-2-2 timings would have done for me. If I got like the OCZ value VX RAM, would I only be able to run 1:1 dividers up to the RAM's limit?

Somewhere, hidden deep in the extreme twinmos thread was a few people telling me that the Neo2 was no good with a booster and high voltage memory. My experience makes me inclined to agree, though I do acknowledge that people have had success with the Ne02 and high voltage, there are also those who havent.

The fact that my UTT ran great on my NF4 and was poor on my Neo2 makes me think that it is inconsistent build quality or components on the MSI that is the problem.

I'm making a fleeting visit to the forum right now, but I'll try to find the page that the posts I am referring to is on later.

I'd love to get some VX4000. Some say it dies soon. I would have active cooling on it, would it die? Also i've heard that dividers do not really matter with the VX and it still performs great regardless. Its either a 3200 and some VX or a 3000 and some TCCD for me...
