By watercooling , +- 22° ambiant temp.

22ºC ambient and the proc is at 23ºC idle? Now that's one truly xtreme watercooling. :eek:

Chilled?
CnQ?

If not, your sensors must be atleast few degrees off. :( Impressive nevertheless!

not chilled and CnQ off and my sensors are ok, just 1.39v and good watercooling.

Core 1ºC over ambient... :hm:

What block do you use? Rad? Pump? How big reservoir?

I don't trust any BIOS/proggy diode reader. I like to monitor temps with thermistors.

SL2 , 1048 , BIP3 , A 45cl reservoir.

But it s this cpu ! with cabne i have 6° more @same vcore.

Monge :toast:

thanks :D only using a arctic freezer64 until the WC is set up tomorrow :banana:
that 148 wont be staying long though, the 146 is stable doing 2.9ghz on stock volts & 1.45V for 3ghz were the 148 needs 1.5V for 2.9ghz stable and currently priming 3ghz 1.55V

Thanks for the info :)

Was the CPU you recieved similar to picture on oc's homepage?

And what's the difference between AMD Opteron UP 146 "San Diego" and Opteron 146 "Venus"?

monge: think one is for 940 ?
11-08-2005, 02:13 PM
tatts

mine came in the cardboard retail box if thats what you mean?
as for venus & san diego, i think one is a skt939 & the other is skt940, always make sure it says 939 before buying coz if it doesnt it will prob be a skt940

Tedy: But I've seen Opteron 146 "Venus" for soc. 939.
eg. here:
http://www.ebug-europe.com/bug/defau...CK939110022944

tatts: Yes, that's what I meant. The cardboard retail box came with Box cooler?

On AMD.com I only find this 146 soc.939:

You can get a good price for it, I guess.
Good luck :)

:lol:

This was purchased to go under my mach II - but even with +ive temperatures via 1.8vcore and folding in the background, htt was still severly limited. I've got an all copper heatsink and 78cfm fan sitting here as well as AS%, I'll get them under that. I've got water cooling here as well. I'm just a masocist who likes to find out how things go with the stock stuff before moving on.

1.8V with stock heatsink, it would of died by now :stick:

Hi tatts,

I have exactly the same stepping 146 as you, but cannot even get 2800MHz stable without silly amounts of vcore! :(

What BIOS are you running and anychance of an A64 Tweaker screenshot?
11-08-2005, 03:04 PM
tatts

i take it youre using a dfi? im using the 704-2bta (use tmods cd from dfistreet to update)
as for a64 tweaker, i havnt touched it yet, left all ram on default for now until i find the max stable clock out of both of them
are you using a ram divider? maybe thats your problem?

Or not using one. Memory bandwidth shouldn't be a huge consideration with the on-chip memory controller. Using a divider to keep it around DDR400 with good timings but a high clockspeed (FSB) should produce good results. I'm using the 2/3 divider to keep my memory is around 204 with and FSB of 310, but my timings are 2-5-2-2 plus tweaks and it's running better than it ever has and I don't think I've topped it out yet.

Read again! 1.8v was under Prometeia Mach II, to try and trick the cold bug.

At -15C Max htt was 265
At 0C Max htt was 290
At 10C Max htt was 320

Under HSF Max htt is 348.

Looks like my 144 Cab2e 0540fpmw compares fairly well, its been running for a week or so, had a few problems with some very twitchy RAM, lacking a bit of bandwidth as a result, running a cpu/14 divider :rolleyes:

Well pleased overall though, my first build with an athlon since my thunderbird 1Ghz :D

I have tried that BIOS and a few others ~ Using G.Skill LA 1:1 or divider (133/166) seems to make no difference, also w/c with temps not going above 45c under load!

I also have a CABNE 0528 GPMW which requires too many volts as well.............! :(
11-08-2005, 03:35 PM
tatts

theres something your missing then if the cabne 0528 needs alot of volts aswell, have you lowered the ldt multiplier? or tried slackening your ram timings?

i get it now, the 1st post doesnt make much sense, even with a mach II 1.8V is abit high, you must be brave lol

1.8v is high, but at least 144's are cheap! I was desperate not to have to use a HSF.
