FSB overclocking, memory

***Zardon*** · May 11, 2002, 11:30 AM

ok I would like to hear from people about what memory they are using and successful FSB overclocking etc..... statistics, benching...

I have my XP 2000+ running at 191MHz FSB. (Coupled to an IWill XP333 with Samsung DDR333 RAM)

It is running at 1910MHz with a 10X Multiplier (I had it at 10.5 but I almost fried it :o)

Its on a /6 PCI Multiplier, with an AGP speed of 255MHz (I know underclocked but my other stuff makes up for it.)

I have a Radeon 8500 64MB Retail @ 300/310 in it (3.6ns RAM)

Its got 512MB RAM, and I am lucky to be able to o/c 2 sticks of RAM to 191MHz on this IWill (Read AmdMB.com

)

what kind of cooling are you using?

Mize · May 12, 2002, 11:04 AM

As my sig states, I run my FSB at 185 with some OCZ/Samsung RAM. I've not volt-modded my Vmem yet, but I could probably hit 200 if I juice it to 3 volts (I'm at 2.7). From everything I've read the best Ram goind is the latest Samsung. I bought OCZ because I got a really good price on it. It's overclocked better than my Corsair XMS2700 would.

When the A/C is off I run with an 8.5 multiplier, switching to 9.5 once the room is artificially cooled.

I am using stock cooling, in an air conditioned room (with a tub hooking in and out of the back of the pc.)

Generic RAM (hynix i think) running at 314MHz. FSB is 157 on a AthlonXP 1600

***Zardon*** · May 14, 2002, 03:34 PM

thats a mighty fine rig you have liquid

LiquidChaos · May 14, 2002, 03:49 PM

Thanks

It is a work in progress... watercooling equipment arrives tomorrow.

It's nice to know your agp bus is running 189 mhz out of spec.

its /6 divider not multiplier.

The goal is to keep agp/pci at 66/33 respective.

P4 1.6A at 150 fsb (600 fsb for cpu 400 mhz for ddr)
retail hsf as 3
load 45c.
1.5 volts on cpu.
2.8 on mem.

just my lowly xp1700+ at 1.6 - the a7a-e doesn't overclock memory past fsb of 138 so bit limited really...only get ~7500 3dmarks with spec in sig

Sorry about the divider, my bad.

But I am using AGP 4x.

(66.667MHz x 4 = 266.6MHz)

(AGP 1x = PCI x2, my PCI = 191 /6 = 31.5MHz, my AGP 1x = PCI x2 = 63MHz, my AGP 4x = AGP 1x x4 = 252MHz.)

kingston ram, 140mhz MAX

Eh?

I thought agp 4x and 2x and such was like ddr and p4 fsb.(voltages aside)

It's just read twice per clock cycle / 4 times ?

Jeff · May 15, 2002, 06:11 PM

and Athlon FSB, true enough, but its like when some people say their Athlon has a FSB of 266MHz, you don't grill them do you.

Ahh, whatever, now you know what I meant.

Bye.

dipstick · May 29, 2002, 03:23 PM

I can run 190 in the winter no problems at all, running at 2.7v. If I get a better case than this old gateway one it might do better. Oh, my mem was OEM cheap stuff from newegg.

AxE · May 29, 2002, 08:23 PM

I was cleaning up my system like I do every month. This time I took everything out, cleaned it and slapped it back. Big mistake. Now I can't go past 150fsb. THis is because the memory was "burnt in" as they say. Blast now it will take forever to get it back like that again!! Must have something to do with the memory contacts!
Let this be a lesson!
