Why is it good for the 3400+? With it's higher multiplier it is not even going to be able to run as high of a FSB as the 3200+ with the same cooling. That makes no sense at all.

Only P4's benefit from high frequency high latency DDR. Anything that can't run CL2 is not good for AMD based systems.:rolleyes:

EDIT/

Stang_Man,

I question the value of knowing the limits of PC4400 in a motherboard that is not really able to use it properly, but it's your quarter. Cheers!:toast:

well, the ram maxed out in the NF7, 235FSB, DC, 8-4-4-3, 2.5 - 3.1V

going to try in an IC7 tomorrow, and a P4C800 on saturday/sunday.

Just because your board can't do it doesn't mean no board can. :rolleyes:

Rofl "my board is by no means an exception" . I've read about 30 diff online reviews and not one got more then 220fsb stable. Even if you read ocz page they mention that this board has stability issues over 220fsb and they are 100% right cuz i cant boot higther then 220fsb with BH5 ram at 3v.

Rofl " my board is by no means an exception" My cuz's nf7's also does 220fsb max, my friend david same thing, mike, john, frenkie, all same max around 220fsb. I know people in other forums that need 1.9-2.0 vdd to reach 240-250fsb stable and you claim u did it at only 1.7v , HIghly doubtfull. Plus your a type a guy that vmods their boards before even trying to see if it works. rofl......tell me thats not true??????

Hey guys, i been reading this forum for like 3 months but i have never registered, but here i am.

Well i have a pair of these sticks my self, I have a P4C800-D vmem modded to a max of 3.25 vdim prommy mach1 and a 2.8c that does 3.9 prime stable everyday.

Well i have been doing some testing with this ram, and this ram really love voltage, at 2.75 i can only get it prime stable at 2.75 at 3 4 4 8 and at 2.85 i can get it stable at 270 with the same timings.


I decided to lower the timings and up the vdimm, tried 2 3 3 7 at 200 fsb passed 30 mins of prime 2 instances, dont have a screenie but it passed.

Wouldnt do anything above 200 fsb no matter wat voltage i used at those timings, then i tried 2.5 4 4 8, 250 fsb at 3.05 perfectly prime stable.

Primed for about 30 mins at that time 2 instances and playing some COD as well while doing this

Ok here are some synthetic benchies at 260 fsb

Been priming at 265 at 3.25 vmem cause 3.15 failed, i guess off the flucuations of my vmem mod for some reason doprs about .15 volts so if im at 3.25 in idle when i prime 2 instances of prime it drops down to like 3.10 or so.

Aww dam, prime failed after 15 mins well only one did :( at 265 3.25 vmem, so i guess 260 is the max prime stable at 3.05 volts

My NF7-S Rev 2 used to run 240MHz all day, every day, as soon as I slapped BIOS d10 on it, the only reason I never had it higher was because the RAM couldn't take it, and that was witout a single mod.

The main reason you don't see much FSB wise out of nForce2 boards in online reviews is because they tend to review with stock voltages, as a lot of the boards have to be returned after review.

Hi all.My first Posting @ xtremesystems :toast:
I have a NF7 and Corsair4000 Twinx 2x256mb Kit.
they Run @253 FSB with 3-4-4-8 Timings.I can boot with
2.5-4-4-8@253FSB , but its not Prime-stable.From 200 to 220mhz Timings are 2-3-3-6.I think with V-Mod and another Bios Version
i can run >250FSB with lower Timings than 3-4-4-8.
Next Week the Shuttle AN50 comes back from RMA and i will test the Corsair on the A64 System.
I have also ordered 2 Sticks KHX 3200 2-2-2-6 to compare which one is better for 1:1 Action@high FSB,:banana:
I think i was lucky with my NF7 doing >250FSB out from the Box.

thanks for your input, have you tested your ram with MemTest86 at all?

All I can say is... :rolleyes:

Online reviews almost NEVER get decent overclocking results. Taking them seriously is ridiculous.

And btw, I waited about 2 months after purchasing this board to vmod it... Please grow up and watch your mouth.

Cant do that as i use my pc and i dont wanna let memtest86 run as i cant use the pc, i dont relaly like memtest86 i did a cycle it passed all tests then i went into prime95 and it failed after 10 mins, i found out that my boards max 1:1 oc is 262 at all timings it would prime at 268 at 3 4 4 8 but then would fail after like 1 hour.

No matter how much voltage or the timings at 263 and above system is unstable at 1:1 ratio which bloody sux, i have a 80 mm vantec stealth over my NB still no luck, i guess i would have to wait to get a new board to see how things go, Maybe a max3 is my next choice. There is one thing i didnt try, 2 4 4 8 i think those timings would go pretty high at 3.15 volts, well i will try and report back to see how it goes.

Grow up and watch my mouth?????? Really????? did i use faul language or something???????? If so please paste it so i can admit to it.

Anyway, Iam 10000000% sure that no stock out of box nf7 can do 230fsb without any vmods or modded bioses. So if you performed a vmod or use modded bios then i dont consider that as "out of box" nonsense. You find me 1 nf7-s that will do 230-240fsb using the latest original bios and i swear to god i'll give u 100 bucks via-pal. I say this cuz iam so so sure of this. Maybe if u have told me u have a DFI mobo i would have believed you since it comes 3.3vddr and 1.9vdd out of box.

Indeed you are wrong..

many and I mean many Nf7-s does 240+ out of the box - plz search though this forum and you´ll see.

btw. lets keep our voices down..

You are not correct. You must have gotten a bad board or two or you didn't know how to set it up properly. Perhaps you used cheap DDR, as it is well documented that NF2 chipset motherboards are particular about the RAM used in high FSB dual operation.

At any rate, making offers like that just makes you look foolish, as everybody knows they have no way of holding you to your promise. If there was a way you'd be paying many people for sure, me included.;)

guys, lets take it easy. we're talking about the ability of XMS 4400 :)

LMFAO, i reckon this thread has gone into a debate about out off the box overclockability of the NF7 LOL, then about online reviewers, whats gonna be next "Why women have a clitoris?"

Stang_man was speaking specifically to the issue of how well the RAM will do in the NF7, so the FSB capabilities certainly are an issue. Your post is a pretty lame attempt at humor and has no relationship to the topic being discussed here.:owned:

So Stang_man, did you try the DDR in your P4 yet? I'm sure you'll find it runs much higher FSB's there.:)

yeah, i am RIGHT NOW :)

i booted up at 280FSB 1:1, hopefully i can run some benches at that speed. I'm currently formatting :)

I'll post back some results asap. hopefully the CPU will max out before the ram, haha

What voltage?

i was using 1.7 vcore, 2.7 vdimm

any suggestions on anything else??

Yeah, set the DDR volts to a minimum of 2.8v. Corsair doesn't even begin to come to life until 2.8v. At 560MHz you're still running under rated speed so you shouldn't need the higher voltage, but I'm assuming you'll want to run faster than 560MHz.

EDIT/

Oops, I was thinking PC4500.:slapass:

PC4400 = 550MHz ;)

i'll try higher vdimm.. i think i'm going to max out the cpu before the ram though...

Dude you ppl were talking about reviewers and FSB overclockability on the NF7 and outa the box overclockability of hte NF7 Has nothing to do with xms pc4400.

Stang_man make sure you turn off all those gaming accelerator features and all that. Cause this ram dont like anything liek that, i couldnt run this ram on turbo, but i could on my A-data pc4000. I just set performance settings to standard.

ok, the RAM easily will do 275FSB, 8-4-4-3, with 2.7V

i'm gonna try higher fsb :)

anyone taken a look at whats hidden under the heatspreaders for chips?

no, not yet..

i believe they're Hynix though..

at 280FSB, 1:1, they are scoring 6657MB/s, 3-4-4-8 in Sandra.

Cough...back to the NF7 thingy quickly...

I just recieved one, booted at 235 outta box, and just did mod and she booted at 247.

Thats with no burn in on board and ram as both are new.

This isnt my board, modded for a friend, so I leave it to him to post how it runs for him after he gets it from me.

Err, also, saying that using a vmodded board to get higher clocks versus someone going stock is one valid arguement, but saying that someone using a modded bios isnt running stock isnt 100% accurate. Changing bios to find something stable and something that allows full use of the board is by no means "cheating" our way to high clocks. Not our fault if someone doenst bother running a board through its paces to see what works best. I say more power to anyone that runs a modded board or bios if it helps. Espec the bios since its not the publics fault that it takes 112 bios releases from a company to get all the bugs worked out.
