Ok I bought a 3800 x2 64. It clocks from 2.0ghz to 2.4ghz easy and even hits 2.65ghz on my watercooling. I've burnt the chip in... i.e I've ran all the usual burn in tests and it hasn't failed on any of them.
It absolutly rocks. Even on my studio apps, Nuendo 3.1 it runs without a crash.
Now when I try to launch eve I get a blank screen, the only way I can get it to run is if I bring the clock rate back to 2.0ghz. Bare in mind that my ram is never overclocked, it allways stays at 400mhz using ratio's. Agp allways stays at 66 mhz.
So why is eve the only program to not like my chip running 400mhz faster. It doesn' even like it running at 200mhz faster.

works fine for my 3800+... EVE seems to have a problem atm with dual core CPUs though and affinity. You have to set the affinity for 1 proc. However, the latest rmr builds have fixed this for the most part.

EVE's uses your CPU so much - it's pushing it more then anyother program that you use; like the ultimate stress test.
Stackless python is weird too - basically if your machine doesn't like running EVE at that speed, then the Overclock isn't as successfull as you think.
EVE is like a box of chocolates |

Strange though, as I run my pc with 2 x uad-1 1ghz dsp pci cards, firewire sound card and I've pushed both cpu's to over 90% and not a crash or anything.
I just thought it was odd that eve would crash the system. I tried lowering the ram speed and upping th cas lvl, maybe pumping more voltage to the cpu might help.

Edited by: MOS DEF on 06/12/2005 19:02:53 Edited by: MOS DEF on 06/12/2005 19:01:41 You CPU is plain unstable. Try rnning 2 instances of Prime95 for 12 hours. If it passes that your OC should be stable.
Edit: My CPU runs at 2.66ghz on water (Winchester 3000+) while i easily can clock it to 2.8ghz for most programs but that doesn't mean those 2.8ghz are stable just because most programs run at that clock speed. You have to find the maximum overclock that is 100% rockstable with everything.
Did you use dividers on your RAM? Mabye it's your RAM that is crapping out and not the CPU. Also check the HTT Multiplier and look if you overclocked your HTT above 1000mhz wich you shouldn't.

Im running EVE on a stock clocked Dual Opteron setup with 2GB of RAM and Windows XP x64. Everthing seems to run fine for me. |

Edited by: Martin Gore on 06/12/2005 19:43:44 Running at stock speeds isn't a problem as I stated earlier It just seemed odd that it was the only program to crash when overclocked.
I did see something about 1200mhz bus speed, could this be the HTT if so I'll have to lower that as that could be the problem. I run 2 x 1 gb 400mhz cl3 ram.

Well, it only takes one program to crash. Odds are eve was using something other programs weren't using.
I was debating which processor to get this christmas along with a mobo/vid card upgrade, was debating between a X2 3800+ or something else around that price range. I think I'll go with a 3800+ after this thread.

Just curious, but what the hell could you possibly need dual 64-bit 3800s for? If you're using an AMD chip that is a 3800 and 'clocks' at 2.0 gigs normally, and is overclocked to even 2.4gigs, that's 20% faster, IE, you're running the same as dual 4+ghz p4 cpus. Are you planning to buy Oblivion and play it in 3200x2400 or what?

The 3800 runs at the same speed as the 3200, 2.0 ghz. the extra 600 on its rating comes from the fact that it is dual core.
You couldnt run Dual 3800s because the Athlon64 cant be run in SMP (the dual core ones have two cores on one chip, actually one piece of silicon, but you cant run 2 chips with the A64) You'd need a 200 series opteron for that (they have an extra HT link for this) (\_/) (O.o) (> <) |

Edited by: Martin Gore on 06/12/2005 20:51:26 I produce records for a living, and run my main studio computer on this set up. Running audio at 88.2khz 24 bit, with lots of vsti analog emulations requires a LOT of power.
I don't want to have to keep exporting or bouncing tracks. I could actually use 4 times this power easily.
Convolution reverb would bring your average desktop pc to its knees just with that effect on its own. I have to use 2 dsp cards uad-1's to take the load of the cpu. These run at 1ghz each as well. So yes... I need the power of x2 3800 ... overclocking 400mhz is the difference between running that extra few synths or ...not

Speaking from experience, after you play EVE for a while you will lose most of your interest in overclocking.
-You will play EVE a lot -EVE dosnt need latest hardware to run perfectly
Before I started EVE looked at overclocking forums everyday, now I couldnt be bothered with even checking the temperature

Being the owner of an X2 4400+, maybe I can help.
First off, make sure you're Prime Stable. That means running two instances of Prime95, one for each core, for 12-24 hours without errors on Torture Test.
Now, you might ask, how do I make it run on each core?
Well, this is part of the solution for EVE, or a possible one. EVE spazzes when you use both cores on it. It tries to pull clock data from both cores, meaning it's actually moving too fast. Think Pac Man on a Cray, to a lesser extent. Instead, you have to CTRL-ALT-DEL to bring up task manager (I barely ever close it anymore) and right click on EVE.EXE. Choose "Set Affinity" and select only one of your cores (both are checked by default). Then EVE works right. Might fix your problem.
TO run Prime95 on both cores, they actually have to be installed in two seperate directories and run from each one, using the same affinity setting process to link the right instance to the right core. Prime95 copies directly (no registry entries) so you can just make a copy of the first Prime95 folder and name it something else.

Fyi, eve works just fine on my X2 4600+ without any affinity crap.
What you *do* need is the AMD CPU Driver from amd page (it's more or less required for dual cores, while with normal amd64 its only needed if you want to use cool'n'quiet).
There's also a hotfix for XP fixing jumpyness problem with X2 and some games (It's a XP kernel bug... hotfix is not yet available from MS unless you call them, but it's available at least from www.amdzone.com .. just search for 'X2 XP bug' on google or something)

That driver tends to have problems with DFI LANParty motherboards and limits OC's across the board in regards to Windows stability. For some it's great, others its not.
I CAN tell you that it's largely due to cache-calls. The 4600 has 2x 512MB cache, where the 4400 has 2x 1mb. More 4400's have problems with older software than 3800s or 42/4600s, not sure particularly why.
Still, even if you don't have to, set affinity anyway. Then you can toss TS/Ventrilo onto the other core and experience no voice lag ;).

Why OC these days anyhow?!?!?!
you have a cpu that can do over 2ghz and you press your luck by overclocking it and then wonder why some things no longer work...as if the OCing didnt 'burn out' a path or two in the cpu.
I learned a long time ago, to oc and burn out the cpu will cost you more then if you just paid that little bit extra to get the speed you wanted... (to make it eve related, you dont undock in what you can't afford to lose, same with the CPU's you use in your PC, don't OC what you can't afford to lose)

It's a bit different with AMD stuff. They make the same series core for 3 different processors, spacing them between each other. 3800+, 4200+, and 4600+ all use one kind of core with a 512mb cache , and the 4400+ and 4800+ use the other. All 3800+ are essentially clocked-down 4600+ that generated too much heat at higher frequencies, so OC'ing them to that level is easy. I can OC my 4400+ to 4800+ speeds with NO heat or voltage changes in its sleep. Unless you got unlucky, most AMDs have that kind of huge jump on the A64 models such as the X2 without any adverse effect on the processor.
Sometimes, though, you end up with a core that just wouldn't have made the grade anyway. If that happens, you're stuck, but ALL AMD X2s will OC at least 200mhz flawlessly. At least, all I've seen.

Yeah, EVE chomps down CPU cycles, which makes duallies and dual cores that much more fun....I played EVE on one core and Vampire: The Masquerade (Bloodlines) on the other a couple nights ago.
What I'd really like to see it love is my SLI video cards. It already does...I run 16x SLI Antialiasing and full anistropic filtering at High Quality settings with no jump at all. Still, I'd like to see more clientside GPU usage....

I only need the x2 for audio, if it was just for games I would have bought a single cpu. Nuendo 3 is duel core optimized, and I actually get more than 100% improvement...not sure why.
Anyhow, if you do audio or 3d rendering, duel core is the only way to go. I know someone who has a 4 x duel opteron... so 8 x 2ghz chips he he. And yes he does use all that power writing tunes.

It really comes into play when doing other stuff at the same time as eve... Downloading 3MB/s from usenet and processing the posts is really CPU intensive. Assigning eve to 1 CPU and grabit to the other really solves alot of problems. It also helps a ton in extracting very large archives.

LMAO @ all the people that think dual core CPU's will help them with game quality.
LMFAO
They aren't written to take advantage of dual cores, yet, where they may help with apps such as photoshop, media player, etc, etc, you will NOT see a massive difference on high-performance games.
*Rubs his hands in glee as he tracks his Athlon 64 FX-55 on the net*
SINGLE CORE IS STILL 4TW!!! WOOT!!!
