Throwing 3.5v down my new Mushkin

[BMORIN]

Throwing 3.5v :) down my new Mushkin (blk lvl2 pc3200) on my new NF7-S and I still can't do 225fsb without '01 crashing to desktop!!!!!!!!!

I did the 3.3v mod on my psu (up to 3.6v under load) then the vdimm mod on my board and started at 3.05vdimm. At that voltage I can loop '01 (5,2,2,2) but when I bump up to 225, no matter what I do it crashes to desktop in a few seconds (even when I adjust timings)

I've tried all sorts of voltages all the way from 3.05 to 3.5 and no go. Im thinking either this ram has issues or has issues with my board. It's funny though that I'm prime stable up to 235 (ran prime before I ran '01).

I bought this ram specifically in mind that that my ram would not get in the way of my FSB, and now IT is the problem.

Any suggestions? I'm running bios 19 but don't know how that could effect my ram crashing to desktop. Should I send it back to Newegg and pay restocking fee and get something else? If so, what?

Makes me mad that I replaced some hpx4000 that would never crash to desktop so I could get some ram that would do better timings

[Evil_Spork]

i assume your sure the mobo will do those speeds right?

[BMORIN]

The board is prime stable up to 235. ARGH, I knocked it back down to 220fsb and just noticed '01 crashed to desktop. I am sooooo ticked.

[Calcu]

What's your vdd at?

[BMORIN]

Vdd at stock. Raising it doesn't help.

I had my nf7-s up to 235 11-3-3-2 with cpu interface enabled 3.0v .. I vDimm modded it - then it went to 240 11-2-2-2 @ 3.2
Level 2 dual pack 245x2 purple Prime 12 hours / 3dmark 01/03 stable .. Zalman + 40mm on north , passive on south .. My vdd showed up at about 1.77 at 1.7 though out the box .. Dunno why ..

[saaya]

hmmmm, what psu and is it one of this new boards with the silver caps? more important than a high voltage is a stable voltage, maybe your vdimm fluctuates too much...

[luihed]

check your sticks one at a time ....maybe you got a bad stick....

[Sovereignty]

You should only need 2.9v for that speed man. Some sticks dont like way too much overvoltage. Turn it down and see how it goes.

[BMORIN]

My vdimm is rock solid under load. I've tried lower voltage to no avail. I've also unhooked my 3.3v psu mod and still same result. I'm at a complete loss. I know these sticks should do that speed without a vdimm mod, that's what is frustrating. Oh, and it has black caps.

[Grace]

If it is Prime95 stable, then it is not the RAM most probably since any errors would result to Prime failing.

I would suspect the motherboard myself too.

Some BIOSes are wonky like this... Try d10 and I'm almost certain things will improve. :)

I have the level2 too bot the pc3500, right now i'm doing ddr500 at 3,3v ddr 510 not fully stable...
Vio mod in the way:D

[BMORIN]

OK, got a little time this morning. I'm going to try to isolate to see if I have a bad stick or a bad slot. If I can't seem to find anything there I'll have to try to flashback to another bios. I'll post my findings in a little while.

[Evil_Spork]

i just found today one of my kingston bh5 sticks is bad... so im RMAing that.

sounds liek you may have the same.

[BMORIN]

I'm still testing, but it looks to be that exact thing - a bad stick. My slots are performing a little differently (one taking more voltage than another to perform at equal fsb), but I'll wait to post my findings until I've finished all possible combos.

Putt CH-5 in and it will fly.. The Mushkin is fine. I have had Level2 in my board, couldn't get 230 stable where my CH-5 does 245 pifast/249 sisoft. Same with all the new NF7-S and AN7..

I AM very glad to hear you say that. ive got another thread (http://www.xtremesystems.org/forums/showthread.php?s=&threadid=24401) right now that is discussing this same thing. How do you think some good CH5 with allot of voltage would do on a new NF7? im thinking it would OC like a bat outta hell, IMO...

[BMORIN]

Yup, a bad stick. One stick is completely stable at 235fsb, the other one fails at even 220. Strange, rma'ing today.

yeah,ive been in contact with OCZ to RMA my bh5 platinum, and they have " a kickass batch of CH5" says one of the engineers there, and thats what they will be using to make the Platinum 3500 now since all the bh5 is gone. Anyhow, one of the techs is just waiting for the engineers to finish binning them and then hes going to ship me out a badass set of that CH5 Platinum 3500 within the next few days! omg i cant wait to get this sucka flyin again. :banana: :banana:

[BMORIN]

Well rma'd the above stick and got back a new one. AAARRRGGGHHH, SAME PROBLEM!!! Come to find out, the problem is that my mobo has a duel channel issue. I can do 240fsb no problem with tight timings in a single channel.

This ticks me off so bad. I have been trying so hard to get a high FSB mobo and ram combo and have failed yet again. This is my 3rd mobo trying to do that. Had an Epox that was garbage, had another nf7-s rev.2 that was good for a week then inexplicably tanked and then now this one that has a duel channel issue. I can't go higher than 200fsb without '01 crashing to desktop. Man, oc'ing sure can be frustrating at times.

[Smokin_Joe]

Wouldn't that be a vcore problem then? Like, not enough of it? If it was the ram you would get lockups or maybe even blue screens. Try the d20 bios if yiou haven't already. I've been using it since it came out and have had no problems.

[BMORIN]

I'm using d19 bios and haven't tried anything else. Guess I will, but I don't see how it could be anything except a dual channel issue with the mobo.

It is not an 'issue'.

When dual channel is enabled on Nforce 2 (and any motherboard) since the memory controller gets twice the load, overclock ability is severely decreased. But from 240 down to 200 is strange, it shouldn't be more than 10-15MHz difference. You might want to check the motherboard cooling.

join the club. ive been chasing this dream of 240+ for the past 4 months, and 2000 us dollars later, ive got squat! :D got my new ram today, hopefully itll fly

You have been told by xDuckx to use bios D10.. why haven't you tried that? Most NF7's will fly with that (not all), so try that first..then try CH-5 sticks as some boards like them instead of BH-5.. If that doesn't work get rid of the board :D

it should. especially towards 2v.

If the price is right, my NF7-S is on sale. :D

[BMORIN]

Strange, everytime I try to flashback using Abit's "FlashMenu," I don't reboot and have to hotswap. I've given up working with this board, guess I'm just going to have to get another.

[bigpoppa]

thats how it goes man, ive got 6 nf7-s on the wall right now, and so do half the peopl on these forums, lol

[BMORIN]

In the future, I'm just going to buy 3 of everything I buy and then pay restocking on the ones that don't OC as well. Someoen should have given me that advice when I just started into OC'ing, lol.
