thats because your 3.3 volt line isnt high enough to supply 3.2 volts correctly. i had the same problem then i turned my 3.3 line to 3.45 and it was rock stable at 3.2 off the 3.3@3.45 just like off teh 5vQuote:

i really dont think this needs to be a sticky, weve got enough already imo.

that actually helped temps a lot, thanksQuote:

The heat and headache generated by these sticks is just not worth it imo, TCCD is much better and more stable, I got like 50 BSOD's trying to get this :banana::banana::banana::banana: stableQuote:

Um if it doesn't do 250 you should contact one of the very friendly and helpful ocz employees on this forum.
I did, a little too late but I did..
A little late? Don't those sticks have lifetime warranty?
no i meant the corrupt windows installation :(
I''ll try to exchange them for some TCCD, and reinstall everything..
you need 3.3 for them to run 250....
did you try 3.4 or so off the 5v rail, 2-2-2?
and what were you thinking installing windows overclocked? should have ran 200x whatever on 2.6 2.5-3-3
i never install windows with my overclocks on, even if i already know its a stable overclock.
I didn't install windows overclocked, I installed it with my old TCCD and it was perfectly stable, then comes the VX and ruins everything, actually i'm pretty sure it's because the sticks are defective, when I get my TCCD back I might be able to load windows, only problem is in frustration I reformatted :(, I know it's was stupid of me, but I initially didn't think it was the sticks fault since I expected them to at least run DDR400 stable, oh well :(Quote:

DUDE!! how come my stupid comment lead to this sticky? well, why is it a sticky??
your stupid comment? have u even posted in this thread?Quote:

I meant this thread, and yes I have (several times) if you read the thread. If you read the first post, it refers to a post in the sapphire gruper thread, which was made by me (the reason for the guy starting this thread). anyhow, that is quite unimportant, my point was that i thought it odd for this to be sticky, that's all. (sorry for the confusion.)Quote:

Third, there are plenty of folks who already run this 5v jumper 24/7 just fine (including me).
Fourth, I can't even recall a single failure as a result someone using the 5v jumper
Frankly, all the concern about the heat on the corner of the mobo where the 5v jumper is borderlines on hysteria. The pwm gets hotter and has no active cooling. The caps in the 5v area were designed to handle the temps.
No where does DFI say using the 5v jumper is "not recommended" for 24/7 use.
there is more heat produced yup. however, the design of that area, allows for tolerance of this heat buildup. otherwise they would not have included the option;) oskar even stated that they put high qual. caps in that area (100K life???).
and to further add, +5 is most definitely more stable then +3 is in terms of voltage. the downside is, the heat buildup.
i have run on +5 for month and a half now. no issues from it.
First of all one month and a half is hardly enough time to say that no damage is being done to the board, also DFI says "use at your own risk" which implies that this could cause trouble and that it isn't covered by warranty, also u don't just need active cooling on that area, u need a very well ventilated case to keep system temps reasonable. What kind of cases are u using the 5V rail in 24/7?
it might be possible to use the 5V rail 24/7 for months without problems, but it's definately not recommended, even by DFI employees, that's why I think this thread is worth stickying, because not all people might want to take that risk, I wish the board had a better way of delivering more vdimm to the ram..
I personally prefer TCCD over UTT/BH-5 because it can give the same performance using less voltage = less heat = quiter system & longer life, at least until there is a better way of delivering vdimm.
my 2ยข..
your right 1 month and a half is not enough time to incur any damage. i go by the presumption that they have tested it thoroughly and if breakage happens, they will warranty it.
I don't remember where I saw the "use at your own risk", might be confusing it with something else, can anyone confirm if damage caused from using the 5V rail is covered by warranty?
Sonic, with all due respect you read like a house on fire.
Read the thread again, your answers are within.
DFI does NOT say "use at your own risk" in reference to the mobo itself
DFI does NOT say that using the 5v jumper 24/7 is not recommended
DFI does NOT say using the 5v jumper voids your warranty
Where are you getting this from? How about some links?
Head over to DFI street were you WILL get the official word from DFI. And that word is that you can use the 5v jumper 24/7. It is only recommended that you use active cooling. Furthermore, any failures caused by using the 5v jumper is waranteed. This is per DFI.
Please stop presenting your opinion as fact. I've personally discussed this issue with Vivian at length via email and I tend to beleive her (a senior DFI USA employee).
EDIT - I checked with Vivian again. The only thing they are referring to when they say use at your own risk is damage that can be caused to the CPU or RAM using high voltages. This is no different than any other mobo with OC options. The mobo is fully warranteed.
I guess I misunderstood them, thought they meant using it could damage the mobo..Quote:

RAM that requires high voltages usually generates a lot of heat, so the last thing u need when using it is another component generating even more heat. I hear the ATI board won't have this problem, that means that DFI could've done this differently..Quote:

Ive been running my ram on the orange line for a month or so at 3.3V 255fsb cas 1.5 with a 80mm fan blowing right on the mosfet. Today, it started crashing in games. Then after a while, i couldnt get windows to boot, its crash after the initial loading screen to a blue screen that said something about memory (no time to read it)
I clocked all the way down to 200mhz cas 2 at 3.1v and it was still no go, so i decided to switch from orange to yellow line.
Seems to be running okay, it booted back to 250mhz cas 1.5 and ran spi8mb.
Im gonna hold off >3.2vdimm for now. Im not saying thats what caused it but maybe ill wait a couple of weeks to see others experience this problem.
All of my above comments were based on direct email exchanges with DFI support and Vivian.Quote:

That said, I agree with you that the heat is an issue some may feel uncomfortable about. But many are running 24/7 just fine with the jumper and zero failures have been reported. That's not to say that there is enough voltage available to fry your memory...which is why they say use at your own risk.
BTW, I use a simple plain jane no name case for my daily rig. LOL....I just moved back to Gskill TCCD from the OCZ VX I was using because running all that voltage to get TCCD type results with the VX wasn't worth it:)
sorry for the way I presented my post, just didn't want ppl to go through what I had to go through, was very frustrated...I hope DFI addresses this issue on their later revisions of the board if possible..
I did the same thing, switched back to my good old OCZ Plat. Rev. 2 :)Quote:

Well to follow up, i noticed when i got back to the bios that the memory option were as if the 5v jumper wasnt set (it was) and i was stuck at 3.2v.
Shutdown the pc, switched the 5v jumper back and forth from on to off back to on and the vdimm options came back. Weird stuff.
