Small FFT's stresses the cpu only. If it fails right away, you need to either lower your overclock, or raise your vcore; there are no other options.

QFT!

If you can't raise your Vcore, try running orthos at 2.7 and see what happens. An immeadiate fail means that you system (most likely the CPU) isn't stable.

In case anyone is actually reading this thread... the heatsink/fan that we've been talking about is otherwise known as the AVC Z7U7414001, and a writeup is below:

http://www.frostytech.com/arti...iew.cfm?articleID=1962

Newegg doesn't sell it, I bought mine off ebay for $7 (auctioned as an "opteron 175 heatsink", the guy had a bunch of them).



I will try rolling back the speed and running orthos again tonight when I get off work. But I played tennis and listened to mp3s and folded for an hour last night, no sweat or hiccups.

Try shorting the thermistor on it. As long as you have a software or hardware fan control on it. You won't want it at 5400 RPM all of the time though. I'm trying to remember what the fan goes up to with the thermistor in place, something like 3500 RPM, unless the case temp goes to a radioactive level. It would be better to have a thermistor that worked off of the CPU temp.

 

[n7]

I hate the stock Opteron heatpipe fan.

Why?

It does cool well, but it also has the incredibly annoying tendency of spinning up & down to maintain a certain temp when fan control is set to be lower, or is too noisy when not.

Glad to hear the X2 3800+ OCs well for you.

The X2 3800+ & a better cooler (not the Opteron one) would have been my recommendation btw.

The Opterons were good back in the day, but these days, the X2s OC extremely well, which wasn't the case back when everyone (including myself) was buying Opterons.

 

[GeezerMan]

There is more than one HSF design used on the Opterons. Some had 70mm and others had 80mm fans. Perhaps one was louder than the other?

 

[Lord Banshee]

I say get the 3800 and buy a better HSF for the money.

I think the Opteron heat sink is overrated personally. I use it on my machine that my GF uses and it doesn't cool that much better than the stock A64 3400+ 90nm. It is loud too, compared to my setup. My HSF my CPU is always between 28-40*C with 0-100% load.

I say get a nice 120mm HSF setup and be happy with cool temps and quieter operation. Also not all 165 can go as high as some mention mine tend not to like anything above 2.4Ghz i can up the voltage up to 1.55v and still doesn't pass prime after 2 hours.

 

[Burticus]

Ok, orthos running for about an hour now at 2.7 stock voltage (1.4) @ 54c, 2.8 looks stable for windows but orthos fails pretty quick. If only the Asrock would give me ....more....power...

Banshee, 2.4 is tops on that 165? I am pretty happy with my decision then. Yeah we all would like Big Typhoons, but $7 vs $30+ for the heatsink is huge. I do like quiet though, so maybe I'll have to toss the fan on this heatsink and throw one of my extra panaflo 80mm's at it... they aren't very high cfm but they are ghost quiet. Besides I'm not going to be running 100% on both cores for anything other than benchmarks anyway...

edit - Oh I just read Banshee's sig again. You have a SI-120 in the gen 1 Sonata, like I have? Do you have to kick the side door shut?

 

[abaqus07]

Thanks Burticus for the thread.

 

[GeezerMan]

It's a for sure YMMV on the HSF. If you read the Frosty Tech and Madshrimps review of the AMD heatpipe, you'll see it is a good size improvement over the standard HSF. A lot depends on your case temps. My personal comparison of the two types showed an improvement by going heatpipe. But remember, I shorted my thermistor to allow a higher fan speed. Not that I run it at 5400 RPM, but I do run it at a greater speed than the thermistor normally allows.
They were more concerned with noise than cooling.

My Opty 165 did an easy, and 24 hour nonstop Orthos proven, overclock to 2.6GHz on stock voltages. Just sold it by the way...
The latest Newegg Toledo core 3800+ X seem to be some of the best overclockers I have seen for the 3800+ X2.
The last one I set up would do 2.8GHz on stock volts

 

[duragezic]

Those X2 3800+ sound like excellent overclockers, and with the bigger price difference now, it might be harder to recommend the 165, especially when it is 9x vs 3800's 10x multiplier.

I think the stock heatpipe HSF is pretty damn nice, for the price. I got the 80mm fan version for $15 shipped off Ebay 18 months ago, and a 70mm fan version with my retail 165.

I tested both of them unscientifically, and as far as I could tell, the 70mm fan version was about equal in temps to the 80mm, and seemed a little better. I didn't have a way to test noise other than how it sounded to me, but it seemed the 70mm was about the same as the 80mm. I read the heatsink on the 70mm is better, while the fan on the 80mm is better since it is larger and quieter. But I couldn't tell any difference in noise so I kept the 70mm version (again, seemed equal or slightly better in temps) and will sell the 80mm version with my 146.

The only other HSF I would consider is the AC Freezer 64 Pro. It is a little better and much more quiet than the stock heatpipe one, but since I already had two of the stock heatpipe ones, there is no way I could justify $25 for another one. Other than that, for the price, the stock heatpipe one is one of the best choices. A $50 Zalman would be pointless as it could maybe get 100-200mhz more at cooler temps, but that is nowhere near $50 as it would be not noticeable except in lame benchmarks.

edit: I actually don't have a problem with the stock heatpipe fan spinning up and down. I know if temps get really high, it will kick way up, but I've not had that happen. Everytime I look at Speedfan, the RPMs are about constant. I believe the sound I hear of a fan spinning faster while gaming is my videocard, but I could be wrong. It only spins up to a high speed, then spins down after I close the game, so it's not up and down annoying.

BTW, my 165 from Newegg was a LCBQE as well, so it is likely that most X2 3800+ will reach just as good of overclocks as a 165, plus has 10x multiplier. Damn, I almost regret not getting one now, but then, the price diff was only about $15, and I got the better HSF.

 

[GeezerMan]

I actually got better temps with the heatpipe HSF over my AC Freezer Pro. About 5 C better. That's with the thermistor shorted.

lol no i don't have to kick the side door shut lol

My opteron used to do 2.6 at 1.45 but in the last couple months it seemed it doesn't like it much so whatever lol.

 

[Burticus]

Can anyone recommend a "softfsb" like tool so I can change the speed up and down in windows? I don't think I need to run full throttle if I'm just surfing, and I'd like to be able to adjust clock speed without rebooting if possible.

I think Abit boards used to come with something like this, but it's been a long time since my budget allowed for a "nice" motherboard.

That fan is starting to tick me off, I need to dig through my closet to see if I can replace it with something quieter. Maybe I can ghetto rig a 120mm to it with zip ties....

 

[SerpentRoyal]

Try RMCLOCK.

Most people use ClockGen. Note, though, that it doesn't enable changing the vcore or the cpu multiplier, only the clockspeed, through the HTT bus.

 

[Burticus]

I played with clockgen a little today.. seemed neat at first, but it doesn't seem to save my PLL settings, and when I attempted to lower my clock back to stock 2000 it locked me up hard. Hmmm.

 

[betasub]

A second vote for RMClock: works a treat for my Opt170 on the Asrock (later BIOS versions allow very high HTT - I tried 333 with no problems - but vCore still has a max of Default+0.5V). You can choose multiple power saving modes/steps and allocate multiplier/Vcore for each.

 

[Kroffty]

I just got my 3800 from newegg
2700mhz at 1.4v stable so far.
How do I run prime95 to use both cores?

 

[Burticus]

Use Orthos to stress both cores.

http://sp2004.fre3.com/beta/beta2.htm

What's your stepping?

BTW - if the Orthos FFT tests fail very quickly even at stock 1.8 speeds, turn off "spread spectrum" in your bios. I had this problem.

I was system stable at 2.8 / 1.4v but Orthos was not pleased. 2.7 runs great.

If anyone is still out there these are now 57.99 free shipping from Newegg. Insane!

http://www.newegg.com/Product/...x?Item=N82E16819103052

I lowered mine down to 2.4 stock voltage for everyday surfing/etc. Lowered the temps a bit. 2.7 is overkill for Firefox!

 

[WildHorse]

When buying an AMD Athlon 64 X2 3800+

do I want Toledo or Manchester core?

Both are same $58 on Newegg.


What about using my Thermalright XP-90 for air cooling and overclocking?

 

[WhipperSnapper]

Would it be worth it to spend $15 more to pick up a 4200 from Newegg with its 11x multiplier and how well do they overclock compared to the 3800's? I figure that it might be easier to get it up to 2.75 with its 11x multiplier (250 x 11 vs. 275 x 10).

 

[Burticus]

The latest cores are Toledo. I would think an XP-90 would do at least as well as the stock cooler so go for it.

I think the 11x vs 10x multi is only an issue if your motherboard has issues with the fsb over 270. Some boards hit 300 easy, others don't. My Asock dual939 used to never get over 270, they've since resolved this with bios updates (or at least the OCW bios's anyway).
