can i go farther Tb 1800 1.53 -> 1.9

[exitnow]

a7n8x v.2
t.Bred 1800 o.c. 1.9
512 mushkin 2700

it is at 152 mhz.

multiple 12.5

that is as far as i went without anybody really helping me. but i am a little afraid. can anybody tell me what they have seen on an 1800. i have a thermalright SLK 800 U. it is pretty nice with my heat. i get about 42 c - 45 load.

i have had it at this clock for a year and am waiting till march 2005 before i buy my amd64. any ideas?

thanks

lower the multiplier, raise the fsb speed and give the core voltage a slight bump to 1.70-1.75v.

You should be able to hit 2000MHz easy, more like 2100-2200MHz.

thank you

up tp 2070Mhz so far

2000mhz is easy. 2200 is a struggle unless you exceed 1.75V
2300mhz is my cap at 1.85V-1.9V

i'm prime95 stable at 2013mhz (175*11.5), and liking the extra mem bandwidth (tho i've had to drop my timings back to 2.5, 4, 4, 10-uber sloooow i know ) on my 2000+ (B0 stepping t-bred) at 1.7v on an A7V8X.

But not prime stable at proper 2600+ settings (12.5*166=2075mhz at either 1.675v or 1.7v (100% stable for everthing else )), tho i bench slightly higher in d3 at the top setup anyway, despite loosing 60-odd mhz. My board doesnt have the AGP/PCI lock, so i cant get much beyond 182mhz fsb (no idea whether thats prime stable, havent tried). Pretty sure your board does, so you should be able to go higher

I can clear 2200mhz no worries, but only at 1.75v+, and in sunny perth with no ac i get terrifying temps with my stock hsf.

Wish I lived in Australia, wanna trade places?

meh, you'd get pretty sick of mid 30'C ambients, doesnt make o'cing that easy a task sometimes

Plus in summer proper we get 20'C mins, have u tried sleeping at that temp in a humid environment

Plus its hard to get hold of components for my rig unless you do it all online, and double complicated when i go home (Jerramungup, ~450kms south of perth )

I live in southern New Mexico, it easily reaches 40C or higher in the summer here.

I'm using a stock retail heatsink, but I had to upgrade the fan on mine, the factory stock one that came with my XP1800+ was pathetically weak in moving any kind of air. I swapped that 2000-RPM fan for a 5000+ RPM one off of an old super-huge PII HSF assembly. Runs great now. Maybe you should consider something like that?

Btw, don't ever get an MSI KT4V-L for overclocking, no PCI/6 divisor means max useful FSB is 166Mhz, and only allowing +0.1v vcore increases means that I can't even bump my CPU with a stock vcore of 1.5v up to 1.65v, which is the stock vcore for an XP2200+. That limits my OC to a measly jump from an 1800+ to a 2000+, although the extra speed of the 166Mhz FSB helps some. (I bought this rig before the NF2 and the TbredB were even available, if anyone was wondering why. Yes, I wish that I had waited a bit, in hindsight. I mostly wanted a full-size board with 6 PCI.)

I've got an Abit AV-10 (KM400) on an extra gaming rig with a Barton 2500+ (non-mobile) running a 194MHz fsb (1/5 pci divider) at stock voltage (1.65v). Don't let the agp/pci bus scare you, 37MHz is no big deal and often times components can run 40MHz without problems. One of the biggest problems I've seen with a high agp bus is the Radeon 9700 series, it won't tolerate anything above 67MHz
