Ok now I'm scared I hit 2351mhz....

Hello all,

I new to the forums and new to OCing so tell me if this is reasonable or is my chip going to die:

FSB:180
Multi: 13
Mem: 5,2,2,2.5
Vcore: 1.68V

CPU Temp: 34C at this time

Result 2351Mhz

Thanks!,

I am using an AMD Athlon XP Throbred Rev "B"

The system did reboot when I was running 3D Mark 2003?

Do I need to up the Vcore voltage? It's floating at about 1.68V

Thanks,
-ES
 
if you are getting that speed at that voltage, then all i can say is "wow". put the voltage to at least 1.8, and see what you get. do you by chance know what week the chip is?
 
I would drop the multi down (I did myself) to around 11.5 and try to hit a FSB of 200 (if your ram can support it).
You will notice more improvement Oc'ing that way then running 13x 180. I just went thru the whole thing myself last week.
I am currently at 2.31ghz myself (201x11.5) 5-2-2-2 and it is noticeably faster then when I had the multi @ 13 and the fsb around 175-180.
Make sure you d/l prime 95 and run it a few hours to check stability. 3dmk isnt that good of a system stress tester, prime is tho 🙂

Welcome to the OC world and enjoy 🙂
 
Better watch out, your PCI bus is getting high and you might corrupt your HDD going much higher. I dont know if mobos yet support a 1/6 divider yet...
 
Hey everybody,

Well I think this is where my rig like to be for now here my system specs:

Epox 8RDA+ mother board
AMD Athlon XP TBred Rev "B"
Western Digital 80 G HD 8 M catch
GainWard GeForce 4 128 OCed 290/540
Volcano 7+ Chip cooler used arctic silver compound
1 stick of Corsair XMS DDR400 512M
Allied Signal 450W power supply
RaidMax case with 6 fans

Sorry not sure the week my chip was manufactured

Well I tried the suggested setting of 11.5 multi and 200 FSB my rig just kept rebooting?
Have I maxed out then?

Anyway reverted back to my last known stable settings of:

Multi: 13
FSB: 180
Mem: 5,2,2,2.5
Vcore: 1.68V
CPU temp: 34c pretty consistant

that probaly means you havnted upped your Vdimm voltage from 2.63 to 2.77 yet, do that first, the Corsair is safe anywhere under 2.8v

if thats not an issue just lower your ram timings till it runs smooth, those ram sticks were made to run 2226 @ 200 I believe, not 2225

I believe the 8rda+ locks it at 33mhz.

Prime95 for 6 hours straight and NO problems so I imagine I will not have a prob with HD corruption.
SHe is running GREAT!

Mine is a 2100 B 0304.

I dont know about slap around, but it SHOULD give a 3.06 P4 a run for it's money 🙂

If you can get a barton up to 200fsb and 2.3, then u could def. do some slappin 🙂
 
Hello all,

Well no I didn't up the vdim I can try that so you say change it to 2.77v and what lower my multi to ay 11 and my FSB to 200?
Will increasing the Vdimm cause heat issues? Probably minor. In anycase thanks for the advise guys I'm still a newbie but this
oc stuff is pretty fun I enjoyed building my own rig opposed to buy a lamo system from DELL or Gateway ect...

-ES
 
Nope, heat wont be an issue upping the Vdimm. I have mine at 2.9 I believe.

Try it at 11 x195, run prime 95 for a few hours to see if it is stable. If it is, try going to 11 x 200, prime it again for a few and if stable, go for 11.5 x 200. I am at 201fsb now, super stable. I am quite happy for the time being 🙂
 
if you take off the heatsink any time soon, write down all the codes on the cpu die. i would love to know what week that chip is.
 
You're gonna have to up your Vcore past 1.68V to run stably at 2.3GHz+, but its also gonna make your temps skyrocket into the 50C range. Don't worry so much about Vdimm, as your RAM is rated to do 400MHz at 2.6V. I would go to 2.7V, as anything more simply isn't necessary (and in fact voids your warranty from Corsair). High FSB don't seem to effect GF4's as much as R9X00 cards, so you should be fine hitting 200MHz FSB sync'd to memory.

His motherboard has AGP/PCI lock.

Yes, up to 166MHz (highest "official" FSB freq. on the nForce2), but I can count on one hand the number of nForce2/R9X00 users that I've come across able to surpass 210MHz FSB. This leads me to believe the lock becomes unstable, non-existent, or non-uniform as you increase the FSB beyond 166MHz. It seems to be more of a BIOS limitation (and possibly a VDD issue as well) combined with the 9X00's low fault tolerance for out-of-spec AGP buses. 8RDA+ users have more luck going over 200MHz, but A7N8XD users all hit a wall at ~195MHz (stuttering or full-out lockups). GF4's don't seem to have the same problems, with many cases running AGP at 90+MHz with no problems. Also, the reports that 333MHz T-bred/Barton owners are modding their chips to run at 266MHz default to get them stable at high FSB speeds also points to some unseen BIOS/divider issue.

actually, i've read an article at vrzone that says that you'll need a V mod for the nforce2 chipset to get higher FSB because it is not getting enough juice
