ok, so i got this ram, and I'm testing it out in my NF7.
it's failing Memtest86 (v1.00), @ 233FSB, 8-4-4-3, with 2.75V (the rated voltage).
is this ram really that sensitive to nForce2 chipsets, and will it do better with the Intel Canterwood chipset?
cause as of right now, it sucks to it's rated 275fsb @ 8-4-4-3 w/2.75V
hmmmmmm
i havent seen anyone on the forums using those sticks :)
Probably too much volt for only 233MHz. Theyre rated to do 275@2.75 not 233@2.75. try 2.5 and 2.6
that's a good point skate, but i'll try that out.
i'd either up the fsb or decrease the voltage a little, maybe to 2.6.
come on marcin, u should know that!!
HMMMMMMM are you guys forgettin that nf7's is limited up to 1.7v on chipset. I suggest u do a vdd mod and raise it up to 1.9 and you might get around 250fsb.
yea i think its chipset limitation, unless that board is known to go higher
But here its not the board, but its the RAMs. You see right there that he have too much volts for the speed if you the rating!!!!
Ask him to run 200fsb at those timings and i bet you it will pass memtest. Nf7's max stable limit is around 210-223fsb but by no means it can reach 233fsb stable without any vmods.Quote:

What are you talking about? My board did 240 stable out of the box, 250 stable with a vdimm mod. 1.7vdd for 250. And my board is by no means an exception - I've seen several threads full of NF7 users with the same experience.Quote:

Just because your board can't do it doesn't mean no board can. :rolleyes:
The fastest computer in the world (OPPainter's FX-51) is using PC3200. Why in God's name would you use PC4400 in an NF7?Quote:

PC3500 CL2 is the highest DDR you should use in an A64 or AXP. Everything over PC3500 has higher latencies and is designed for P4 i865 and i875 computers. AMD does not benefit from DDR like that, so not only is it a waste of money it's actually slower because of the latency.:toast:
agreed, i bought some 4400 just the other week 1gb of it, and rma'd it with all the other intel crap i bought, then got myself an a64 rig with 1gb of mushky lvl 2 3500 which comes in tomorrow!
Sorry your board is an exception, out of the box 240 FSB very few of them. Out of the box for NF7 is common to get 230 and with d10 bios. I´ve tried like 10 of them and basically all of them did the same. Not even one 240 out of the box. You know your board is an exception because you have one of the highest fsb on nforce2 mobos (congratulations by the way ;) ). I think those 4xxx sticks are not designed for nforce2, anyway try to mod your board and see if it helps.Quote:

I've only had 1 NF7 and it topped out at 237MHz without vmods. This is one of the reasons PC3700+ is a bad Idea on an AMD based motherboard.:)
I cant say that this arguement is entirely true. BH-5 ram requires very high vdimm in order to achieve desirable cas/fsb and high vdimm is a KILLER of A64 chips. This is why bh-5 ram is not always the best choice. If you can get about 250fsb with 3v~3.2vdimm then your fine. But if you have to use 3.5~3.8v then stay away from bh-5.Quote:

you guys, i'm running the ram with a divider of, 3/5 :)
the fsb on my NF7 is really low, but the ram is up there, i'm just trying to max out the ram!!
and "why in God's name would I use PC4400 in a nf7?" well, I got the ram for free :)
how did you have those RAMs!!!!!!!!!!!!!!!!????????????
:slobber:
Pc4xxx is the worst possible ram for an Nforce, its just not made for that (in fact I am not sure it should be made for anything at all ;)) . Get 3200 or 3500 w/ low latency.
Well that's even worse. When you run an AMD based computer with a divider the system takes a huge performance hit. Bench it and see for yourself. 1:1 is the only way to go, especially on NF2.Quote:

For A64 3400+ PC4000 is okay. Even good.
Yes, but for a bit less $$$ you can get some PC 3200 cas 2-2-2 and have better performance.Quote:

yeah i really dont like pc4xxx. bad timimgs for nforce,
Not guaranteed though.
guys, you're missing the point.
i am wanting to test the max FSB of these chips in a nforce2 setup right now, and then i'll find out the max fsb in a canterwood
thanks Gamer, i'll try them out in a P4C800 and a IC7 asap
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.Quote:

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.

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.Quote:

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?Quote:

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.Quote:

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.Quote:

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.Quote:

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 :)Quote:

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 vdimmQuote:

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.Quote:

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.Quote:

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.
here's a screenshot:
280FSB, 1:1, 3-4-4-8
Nice bandwidth there mate:toast:
I'm getting a stable max of about 288mhz out of the XMS4400 at 2.8v CAS 2.5 7,4,4 on a P4C800/P4C2.4ghz. I'm gonna raise the timings and go for more....
my setup wont boot at cas 2.5 :(Quote:

how much bandwidth you getting?
Which memory are you using and which timmings?? How much vdd and which cooling for the chipset?? Bios D10 I guess no??Quote:
