Highest AMD HTT speeds

Heres mine, had this rig running almost 24/7 solid for almost a year. Great rig. Sold it to my mate and its still clocked that high

X2 3800+ @ 2.75 (was Running at 2.8Ghz but not 100% rock solid)
2Gb of GeIL Ram
ASUS A8R32-MVP

Good 1 mate. I had an X2-3800 (939) which topped out at 2620mhz. Then an X2-3800 (AM2) which crapped at 2520mhz..both under wc...in this very mobo :confused:

I've had no luck at all with any of the 38's

Cheers mate

That O/C was under air cooler as well. Zalman 9500LED, full load low/mid 50c.

Those 939 3800+ X2s are great clockers, theres a database on here somewhere.

Got same CPU but noticing that your o/c is considerably quicker. Is this because yours was w/c? I'm pretty much new to o/c, everything I've learned has been thru this forum tbh. Can my 939 +3800 be overclocked more without watercooling? I'm totally air cooled with good air flo...(i think)

El Jimben · 13 Jun 2007 at 20:46

Are you having trouble going higher on stock volts then or have you just not tried pushing it higher? Most x2 3800s do a fair bit more than 2.4GHz, check this thread out - http://forums.overclockers.co.uk/showthread.php?t=17578954&page=1&highlight=3800+thread

Also, what CPU cooler and RAM are you using?

Modjo · 14 Jun 2007 at 02:12

I've got a Zalmann CNPS 8000 CPU cooler (recently bought for £25) and my RAM is V-Data DDR400 3200 (2x1gb). My mobo is new (heard good reviews on its clockability) but in the o/c process the v was the last thing i upped. It can be upped but only to 1.4 max. Have tried lowering the multiplyer to 8x and 9x and upping the bus without upping the v but then I got scared as it wouldn't post.

SOLDNER-MOFO64 is that vista ??

or a skin for XP, not seen vista yet, kinda waiting a year before i make the jump....

I have the deluxe version of the board you have and it's a pretty decent clocker with a lot of features. What's holding you back currently is your RAM because you're running it at 1:1 with your FSB so currently it's overclocked by 40MHz. If you drop the RAM divider to 333, this will make the RAM run at 200MHz against the 240 MHz FSB and this should let you push the CPU more. Also make sure you drop the HTT multiplier to 3 after the FSB goes over 250.

Thanks for that

(Also seen the +3800 thread that you mentioned) but have a few more relevent questions 'coz I'm still a newbie to all this. (Started 2 months ago!). How would I drop the RAM divider? In BIoS I have a RAM Memclock Value setting which only gives me 8 settings.. 100, 133, 166, 183, 200, 216, 233 and 250. Are these the same as the divider that you state? Also my HTT multiplyer goes up in MHz. 200, 400, 600, 800 and 1GHz. Is the 600MHz the x3 option? (200MHz stock x3 for a wild guess).
And finally I have a slightly poo PSU. A £30 Mercury (so called) 500W (yeah right!) PSU. Could this also be holding me back? Cheers

EDIT!....

HAve done what you advised (I think) and have managed to squeeze a bit more out.

mmmmmmm, love it.

Also whats the two bars u have at the top and right??
They look like Linux, but it looks like windows ?!?!

Cheers

It's just toolbars I made myself mate. If you create a folder and drag it partially off the edge of your desktop and let go, a toolbar will appear. You can customize the title, text and size to suit. Any shortcuts you place in the folder you created will appear on the toolbar

very nice cloks tho, and love the WC.
reminds me of the cooling tower my friend and i devised from b&q scrap bin. managed to hold ambient water temps at a 48hr nonstop lan xD

heheee gotta love ghetto cooling mods

Yeah it's Vista mate. X86 (32bit)

Wish my mobo would be stable at 300+

EDIT: I Do have my mem running in 1:1 though, which is nice

Nice clocks.....nice memory too, that your highest yeah? I notice your HT bus is @ 1000mhz +.

I take it you've tried lowering it to see if there any FSB headroom left?

paradigm · 24 Jun 2007 at 15:30

Not tried lowering the HT multiplier lower than that yet, and not tried the RAM at a lower divider.

Tbh, this board has never been great at clocking (AN8-SLi).

I've seen a few go 3Ghz plus on that ABIT mobo. I think you'll defo see more FSB with HTx at 3x and maybe drop a memory divider aswell. Which memory do you have....DDR500 or 600?

Also, what cooling you runnin'....stock HSF?

paradigm · 24 Jun 2007 at 15:47

DDR550 (PC4400) G.Skill RAM, and I'm on a swiftec MCX462 HSF with a 92mm fan.

Temps idle at around 34ºc, and load at 51ºc.

Not bad! As far as the RAM goes, I would drop it down to a 133 divider for now, that way it will be running slower than 200MHz and you'll be able to see how high you can push your CPU. Don't worry too much about overclocking your RAM, as the increased CPU speed will be of greater benefit.

Also, go into the memory options in the BIOS and change the command rate from 2T to 1T, as this gives better performance. I think it's called CMD-ADDR timing or something on this board. You're right about the HTT link, x3 = 600MHz, x4 = 800MHz etc. You should change the PCI-E link width to x16 too, it's only running at x8 currently.

Anyone got any ideas why multipliers don't seem to work with my CPU?

I thought all A64's allowed you to choose lower fsb multipliers than stock?

Are you dropping your FSB back to stock when you attempt to switch multi's?

If not your ram speed will increase as a result.

Like this.....

paradigm · 24 Jun 2007 at 16:26

No, what I mean is, say for instance I set 315x6.0 in the BIOS for the CPU, I can set that no problem, reboot and go into bios where it will report CPU speed as 1890MHz, no problem.

Continue to boot into windows, and low and behold it craps out. I find this odd as the CPU is well below stock speed, anyway, assuming it was the FSB, I set 275x8 = 2200MHz. I know my CPU can do that speed with ease, and I know my mobo can be stable at that FSB.

Bios reports 2200MHz in uGuru, get into windows (Vista Ultimate x32), and CPUz reports that my CPU is at 275x10! It doesn't matter what I set the multi to in the bios, windows always reports 10!

Hmmm that's weird.....is this with the HTx at 4x yeah? That'd explain the crapping out early as your HTT speed would be 315x4 (1260mhz). Still it doesn't explain the cpu multi. You flashed with latest BIOS yeah?
What Vcore you runnin' also?
