xp1600+@1900mhz,nforce2 200mhz fsb

[jcamp205]

ok first time posting here the hard forums are down.🙁 ok so last night got this crazy idea to put my computer outside my window just to see how high of a overclock i could get it was a cold night 33F.

my system goes like this xp1600+agoia 0213, asus nforce2 ,8500 128 meg retail , 256 mushkin pc150 ,256 samsung pc2700 . ok so i got it running stable @1950mhz setteled on 9.5 x 200 fsb 1900mhz . my cpu stayed at 42f degress now if i buy some better ram pc3500 will i be able to run a 200 fsb or will the nforce2 chip need water cooling to run stable. the reason i ask as i see in some of the reveiws people are only getting like 185 or so fsb. just recently got into overclocking and am thinking of going h2o route for cooling.

at 9.5x200 fsb in sandra i was getting like 2900/2650 in the memory bandwidth score is thta good for my setup at that speed?? 3dmark2001 i was scoring 11000 with this radeon @330/330 getting a 9700pro xmas

the reason for this post is i would like some experts advice on what cooling set up i would need to sustain these speeds indoors lol .

damn i've been waiting to see somone post this, guess i'll be buying the epox version of this.

200fsb would be freaking sweet, i'm running mine at 166 (same chip as you)

but my U160 card does not like out of spec pci

and i am running water already so this shouldn't be a problem

does your board use chip diode reading for true temp?

my agoia runs as low as 32C on water (true temp)

nice OC what kind of frames you get in UT2k3?

256 mushkin pc150??
you dont have that in your system do you...?

dannybin1742: i think most, if not all nforce2 boards, will lock the pci in spec along with agp

When I was in the dorms last year, I had my fan sucking cold air from outside right into my cpu

lol sorry sorry pc2500 its speced to run @150 lol

ya thats the true die temp never went above 44f it would post at 2000mhz but would lock in sandra

i didnt get a chance to run ut2k3 i really didnt want to leave it outside long scared of condensation i will do it again probally tommorow and get some ut2k3 results i had to run really lax ram timeings to get it to 200 i think my sandra score would have been better im getting 2 sticks of geil pc3500 cas2 512megs and a 9700pro so i guess ill set that out side the window when i get it i would really like to sustain these speeds indoors so what kind of cooling would i require im thinking that since the mobo temp was so low 29f was the reason i got to 200 maybe a nice water cpu and chipset block with either pelts or make a chiller


yes locking the agp to 66 does lock pci to 33

i would say get this mobo or one with the nforce2 you wont regret it i have not had one problem and a nice feature is when i overclock to high the system gives me a error on start up. usally i have to clear the cmos when i clock to high i have not had to reset the cmos once pretty nice feature i think the talking diagonstic thing gets annoying

as far

According to all Nforce2 reviews I've seen, PCI is locked to 33MHz on most Nforce2 boards. AGP will have a lock which probably ranges between 66 and 100MHz.

From the Anandtech review:

Abit:
The NF7-S BIOS version we received contained an AGP lock set at 66MHz, but we were unable to find any PCI lock set at 33MHz in this BIOS. We asked ABIT why the AGP lock was included in the NF7-S BIOS but not the PCI lock, and we were basically told that the only reason you don't see a PCI lock in the BIOS is because ABIT doesn't want users fooling around with PCI frequency, especially since it offers virtually no performance gain.

ASUS:
The A7N8X BIOS definitely does contain an AGP bus lock at 66MHz. However, what about the PCI bus lock at 33MHz? For this question we headed over to ASUS and asked them what was going on. ASUS's response was simply that they have a PCI bus lock set at 33MHz and that you have nothing to worry about as far as running your devices out of specification while performing FSB overclocking.

Chaintech:
Even though there's definitely an AGP lock in the 7NJS BIOS, there isn't any visible PCI lock. According to Chaintech though, the 7NJS does indeed lock the PCI bus at 33MHz, there just isn't an option in the BIOS to tinker with it. We have no way of independently verifying this ourselves, so take it for what it's worth.

EpoX:
As far as we can tell, the Epox 8RDA+ contains just an AGP lock, but no visible PCI lock. We've haven't been able to get confirmation from Epox as to whether this board locks the PCI bus at 33MHz or not, but we'll update this section as soon as we hear back from Epox.

Leadtek:
While the Leadtek K7NCR18D has an AGP lock in its BIOS, we were unable to determine if this board enabled PCI locking. We asked Leadtek about this, and so far we haven't received a clear response. Once we find out what the deal is with PCI locking, we'll update this section. 12/04/02 UPDATE: Leadtek has finally gotten back to us and, according to them, their K7NCR18D does not include a PCI bus lock at 33MHz, and therefore the PCI bus will be overclocked at certain overclocked FSB speeds.

MSI:
We still haven't been able to get confirmation from MSI as to whether the K7N2-L locks the PCI bus at 33MHz. There is an AGP lock at 66MHz for this board (as with all nForce2 boards). We'll immediately update you with more information as we receive it from MSI. 12/04/02 UPDATE: MSI sends word that the K7N2-L indeed does not have a PCI bus lock at 33MHz, meaning you will overclock your PCI bus to a certain level at a certain overclocked FSB speed.

So, it seems that only Leadtek and MSI from this bunch have no lock on the PCI.

200mhz FSB is slower than 166FSB (at the same CPU clockspeed) on nforce 2's


I've been complaining about this for days - and yes that's even with CAS 2 ram - I posted a massive post about it trying to figure it out, but it seems no one gives a damn

Sure if you get 200mhz fsb AND the clock speed higher (due to the 200mhz fsb) great, but 166mhz fsb is faster at the moment for some reason.
See tomshardware's roundup of nforce 2's - and just about every other review.

I'd love to know why.

On a practical note, it's probably not good for your hard drive to be run at that temperature. Or at least make sure not to fire it up after it's reached 35F. I recall reading some of the acclimation instructions for my old Quantum Atlas 10k... they had a chart showing that if the drive reached such-&-such temperature, let it acclimate for such-&-such hours... or DAYS. Condensation on the platters bad.
