Did you try the same memory slot with both units ?
If its just failing everything , it might have been static damaged , or there could be a problem with the slot you have it in

It's hard to make any judgements on what is availabe from newegg. I do not buy from them, so there is no way for me to see part numbers, etc. I only buy parts when i can see them ( at least memory and cpu's!)
The value VX should be a bit safer for results... considering what ryanp says. you've got this info from the namufacurer themselves, and I'm just a user, right?
Just use your best judgement. Nothing is ever guaranteed...but the valueVX seems almost that way. The whole reason for me posting was just really to show that just because memory is cheap does not mean it will not perform.
OCZ gives a better warranty, and service. The v-data..should anything go wrong... I don't know what i would do...LoL.
Up here in Canada, this v-data gives me almost similar result as this valueVX. i cannot get the right VX here, so i have to make do with what i can get. You have more options...
I got some duds :down:
Guess that's the chance you take with overclocking. They won't even do 240 with 3.6v
Guess i'll hang onto these for a later build, they aren't gonna do me any good.
So what can they do @3.3V? 230 2-2-2 for 150$ iwouldn`t be too bad i think ;)Quote:

I did test it on all 4 slots in by itself. So I know its not the slots. Since the other mems I had performed just fine.
The one stick that I do have is running VERY nicely :) Can't wait to do it in dual chan.

you can rma just one stick if you are satisfied with the performance of that other good stick
"dual channel kit" is just markgeting hype unless they are tested, in this case which they arent
update on my situation:
before:
3.1v - no post
3.2v - 240 something, i forget and havent gone this low since initial trial
3.3v - 245 failed? i forget either it passed or failed at that voltage
3.4v - 250 stable
3.5v - 255 fails with like...600-1000 errors on the first pass of memtest # 5
now:
3.5v - 255 fails with only 2 or 4 errors after every 3 to 5 passes
3.6v - previously untested cuz i dont want to go this high, but now testing with over ten passes of memtest #5 at 255
just want to test at 3.6, definitely wont run at that voltage. 260 has 90,000 errors at 3.6v...lol
I had like 10000000 errors at only 240, you got a pretty nice set.
guys, have you thought about trying 2-3-2 and seeing what speed you get from this value VX, its not much slower(although 2-2-2 is nice) but it may gain you some extra MHZ on the cpu.
Mine wouldnt pass MemTest at 200 6-2-2-2 2.85v but i only tried them for about 20 minutes.
thats out of spec thats why, even for vxQuote:

does most VX do 2-2-2 at 2.85v?Quote:

2.85v is not enough for 2-2-2 timings... even in Anandtech's review of PC4000 VX they mentioned 3.0v was bout the norm for getting 2-2-2 timings on UTTQuote:

Anyway, it's rare that you'll stumble across a set of VX that'll run 2-2-2 timings with only 2.8V to 2.9V. However, I was able to pull it off for 20 loops of Memtest the first night I had the RAM. This doesn't mean anything but I just wanted to put the word out there that some sets may be able to do it.
yah there are always "golden" sticks or CPUs. I'm just hoping to get the 240s at 3.3 or less on my board with a gig. Anything else is gravy. I may be selling one of my two infinitys and getting a DFI ut250, them I'll pobably use these in there and see what the extra voltage can do. But til then, unless I get around to modding my Southbridge 240 is all I can do without dropping sound/usb. Except for changing my APCI setting under my hardware manager and that fuggers Doom3 for some reason.
k another update from me:
earlier i said i had it at 255 at 3.6 with over 10 passes.
i left it running and went to work and just got home...
4 errors after six hours
i can definitely see these errors going away with longer use of these sticks, since i have a largely reduced amount of errors at 3.5v...
but i dont care and wont run at 3.6v versus 3.4v for an extra 5 mhz....lol
well after some testing so far what i have is :
3.2v up to 245mhz
3.3v up to 252mhz
both at 2-2-2-(5-11)
seems that it can do more but my mobo/cpu might be a problem
okay, two posts up i just said i got 4 errors after six hours on memtest 5 at 3.6v 255mhz
just a reminder: at the beginning, i was able to get 250 right off the bat with 3.4v stable...even at 252 i got like 1000 errors..per pass
after about a week of use (mostly priming)...i was able to get only a couple errors every few passes at 255mhz at 3.5v
it took me 3.6v to hit 255 more "stably" (even though i got four errors after six hours)
mind you, i dont consider any errors stable, just couldnt find a better word at the moment
anyways heres the point after that brief flashback:
right now i just made my 20th pass at 255mhz at 3.5v error free!! whereas at the beginning i'd get like...600 errors every pass and then a week later, a couple errors every few passes to now....no errors after 20 passes!! i never believed in burning in until my previous set of Twinmos utt and now this set. i am now a believer.
EDIT:two errors after 22 passes :mad: i jinxed myself.
I'm going to get into this more over the weekend, but before I go out for the night, I have a couple of questions.
How would I know if my PSU is preventing me from OCing more? I'm getting the feeling that maybe it's my PSU, but it very well could be just because I don't really know what I'm doing yet. :D Would there be some way to indicate that my PSU isn't enough?
The other thing I had happen is new to me (I've never OCed RAM before so that's part of it). I set my timings for 2,2,2,5. I lost my BIOS. System rebooted and no BIOS found. I had to use the jumper. Went back in my memory timings and pin-pointed the problem. When I changed my Ras to Cas timing from Auto (4) to 2, I lost my BIOS again. Is this normal? I've never seen this before.
Right now, my memory is running at 200MHz, 2,3,2,5 1T. The 3 is from Auto because I slowed the memory down to 333MHz with a 240 HTT.
Earlier I had my HTT at 250x10 1.5v on the cpu. I lowered my CPU tonight and played with some memory timings and I had that at 220 2,4,2,5 at 2.75v (I think). When I set both at those speeds together, Windows won't start. That's why I ask about my PSU.
I'll read up some more tomorrow and get back into this.
If your PSU does not have at least 28A available on the 12v rail, in my experience this will cause issues when iverclocking, I prefer a quality PSU with at least 30A on the 12v line. In the case of a nwer "split 12v rail" design add the 2 lines together ahd this is your total. With a lesser PSU you can pretty much be on problems, especially with a high end grahics card.Quote:

im going to pick up a powerstream my next rig anyways... but i sure do love this fortron...
Different manufacturers rate "differently". If you were using that 18A on an NF2 rig you would be fine. A64 has much higher power requirement, not to mention the needs of a higher end vid card.
I love my fortron too but since I got my 6800 my 12v(previously tweaked up a hair) has been dippin under 12v :( . Time to start huntin for a new atx 2.0Quote:

In the meantime, I've made the connection that if I set CL and Ras to Cas to 2, I have to reset my BIOS with the jumper. Here are some results I'm pulling off this sheet I'm writing things down on. :) My mobo won't let me go over 3v, so I guess I'm not going to get too much out of the memory.
SuperPi Failed: 2.9v 3,4,4,8 1T 230 MHz
SuperPi Failed: 2.9v 2,3,2,5,7 1T 225 MHz
SuperPi Passed: 2.6v 2,3,2,5,7 1T 200 MHz
Given those numbers, what else could I try that might offer better performance (higher MHz, looser timing examples that might be more efficient than what I have now)?
Up until yesterday, my CPU was going at 250x10 and was stable. Something changed from then to now because I can't get over 240x10 with my voltage as high as I can set it (1.55).
So I have my memory at DDR333 (200MHz) with my HTT at 240. It looks like I can get the memory up to 225 Mhz, is there a better configuration I should be using?
Someone show me the way! lol
DJ,
Are you now using Value VX or are you just asking about your current rig?
:stick:

i agree with your assesment though, im really worried about how this will handle A64\new videocard and all of my crap, every molex is already filled heh...ive heard of fortrons going way over specs before, but that may be pushing it...
Whoops, sorry, the Value VX.Quote:

What I have going at this moment is this:
CPU: 250x10, HT=4 for 2500MHz, 1.58v (that's as high as I can juice my CPU, is that number safe?)
Memory: 208MHz, 2,3,2,5 1T 2.8v
I did get my best SuperPi score on the 1 Meg (only one I've been testing) of 35sec (got 36 with my previous ram). And also reached the best Sandra Cache & Memory which was over 6800 MB/s.
The memory won't run at 250MHz (best for me so far was 225MHz), but I feel like there has got to be a way to get more out of the memory w/o losing so much CPU.
You need an OCZ booster or a Vdimm mod, VX loves volts up it's arse.
I agree, more volts. 3.4v-3.5v is best. I know you are limited on the ASUS SLI. If you had the DFI SLI board 3.4v would be as easy as setting it in the BIOS. :)Quote:

i needed 3.1 with my twinmos to hit 2-2-2
with my current ocz, i forget what it required to hit 2-2-2...either 3.1 or 3.2, its only been a week or so too...lol...gettin old :(
i heard the pc-4000 has a bit easier time hitting 2-2-2 at 3.0...but i dont think i've seen 2.9v hit 2-2-2
spend 30-40 bucks to get the ddr booster if you dont feel you can handle a mobo or psu mod
either that or sell the ram if you cant give it the juice....lol
