G400 (vanilla) MAXIMUM OVERCLOCK SPEED

[Aplek]

For once and for all, let us put together a survey to see what is the
maximum overclock speed the G400 (non-MAX) can achieve. I have an extra
pentium fan with heatsink available. I'm planning to cut the heatsink into
4 and paste them onto the memory chips but I don't know if it's even worth
the effort. Anyways, here is my overclock speed:

DLL - 300
Main - 150
RAM - 200

using MGA Tweak.

I did the heatsink to memory trick (on both sides) already because if nothing else, it'll make it last longer

PLL: 418
GCLK: 167
MCLK: 209
WCLK: 167

Dividers are: 2.5, 2, 2.5

Well, my G400 SH 16 Meg OEM does:

Fo: 305.1Mhz
GClock:152.55
MClock:203.40
WClock:152.55

32mb OEM DH

401 PLL
160mhz gclk & wclk
200mhz mclk

runs great.

[Aplek]

Rickn, did you put a fan & heatsink to the memory chips? What's your setup?

[DuRaNgO]

Paradox, you should go with 2, 1.5, 2 setting as the -5ns memory can go at least to 220

Aplek: Not to the memory chips, but I did screw an old pentium fan to the G400 heatsink.

I have a P2B-F and a P3 550. The G400 is OEM with 6ns memory. 200mhz is the cutoff - at 202 artifacts begin, but 200 works great. Can't complain for a card that cost me $150, and kicks the shit out of TNT2 and Voodoo(doo)

Good Idea. I'm trying it right now with system PLL at 330mhz... looking for "snow" now...

DuRaNgO!

I almost got the excact same computer as you do, except the hdd.

And I just must ask you....
What settings do use to get your cpu to 620?
