First thoughts on my X2 4800+...

...are that I am not impressed.

Ok, I'll put that statement into context.

Have seen no improvement in multitasking, which I would have thought would be the biggest gain. Used to have an San Diego clocked at 2.8, that ran sweet as a nut. I cannot notice any improvement over my old chip when running more than one task. For example, I do not multitask to much anyway but, I tried running F@H when burning a disk and playing COD2 before I put in the chip, OK, the game ran a little jittery but, I've replaced the chip and the game does not run that much differently.

I tried running benchies and again I am not impressed. The usual benchies i.e super PI are noticably slower by a long way, I take it the programme is not optimised to run off both cores, is that right?

The usual progs like Sisoft Sandra, 3D mark etc show an improvemnet in CPU scores but I cannot see it in my day to day experience. In other words, game playing is slower, day to day windows is slower, certain multitasks seem slower, which obviousy cannot be right. So what is wrong?

I have tried the AMD optimizer, and have added the MS hotfix, both of which do not seem to have changed my system one iota. I'm going to try overclocking but I am not feeling confident.

First attempt was to take my ram out of the equation by seriously underclocking it through the divider. Tried to up the FSB but the chip would not post. Chip is seated properly with AS5 and temps under load (both corers running F@H) are 47 degrees. This seems hot to me, as my san diego never got over 43 degrees in the heatwave.

It seems there is no headroom on this chip at all, cannot believe it is seated incorrectly as I have installed many many chips before so what could be the problem?

Your thoughts ladies and gentleman would be appreciated as always.

P.S. Only reason I haven't put my old SD back in is because I do not want to have SiriusB overtake me in F@H, taking a performance hit for the good of mankind is still a little hard to take, maybe I'm not as charitable as i thought.

P.P.S I seem to be accessing my disk a lot more than I used to, I know this cannot be relevant but it is the case. I am now running my comp at stock everything as opposed to my sig which I was running before and it is noticeably slower in all things, including openeing windows apps. Thoughts?

OK have installed the driver, the optimizer and the windows hotfix, havent edited the registry as stated here http://www.xtremesystems.org/forums/showthread.php?t=81429 because I do not understand why Microsoft would release a hotfix that needs to enabled manually through the registry. EDIT have now edited the registry.

Has anyone used the regedit?

To answer some earlier posts I have a Hiper r 580 so should have plenty of juice. Yes, I do see two graphs in task manager.

i've got a 4800+ 2 weeks ago.
iam now running at 2.8 ghz stable and don't notice any difference
from my 2.8ghz 146 opteron
i don't have any drivers or optimizer installed.

Can you give me a few more details on your overclock. Setup, bios info, divider, fsb, cooling and your temps please.

I have been fiddling around for most of the day and am struggling to get stable over 2.65. My load temps never get past 51 degrees so its not a temp issue with me.
 
Well I spent a fruitless few hours yesterday trying to clock the 4800+ and it won't. The best I have been able to get is 2.6 stable, although I have throttled that back to 2.56 because of the amount of extra vaults I have to pump through it.

Temps never got over 55 degrees and that was putting 1.5 vaults through it at 2.75. I had no problems getting into windows etc but as soon as I ran stress tests it failed.

Tried every variant of multiplier and fsb with no results. Quite dissapointing really, but still happy with the purchase as being able to multitask is a boon.

System is noticably slower in single tasks though but thats to be expected as my 3700 was clocked at 2.8.

Hi 2bullish have you given it time to burn in had same problem with my 4800 x2 that i just picked up friday (not from OcUK prices to high. take note OcUK) would not clock over 2540 FSB, been running prime over night set to the most stable clock left it on went to bed, has of to days post got it up to 2710. still more testing to do.

*** settings are you using to get that clock and whats your hardware spec and temps mate?

put simply mate, dual core is un-necessary unless you want to encode video whilst playing a game or something like that.

I know, I have argued the case myself but I still want two chips rather than one, as I have already bitten the bullet, I just want to know how to get the best out of what I have now.
 
Well after much sweat and gnashing of teeth I've finally got to my max.

11.5 x 230 = 2645

Volts 1.45

Temp using GO blend 54 degrees

I can boot into windows and use the computer happily, including gaming, at 2.75, but any significant stress testing stops.

The same core (core 0) always craps out first, Prime95 run on Core 1 will happily run for ever at 2.7 for hours. So I've been limited by one of the cores.
 
Thought those temps were high so just reseated the HSF and I'm down to 52 degrees.

I have to stress its very hot in Mnachester tonight, really close, so my ambients are high, normal weather would probably have that down to under 50.

Think I might invest in some superior cooling, probably a Ninja, thoughts people?

Why not go water if your want to overclock in future?

How many different air coolers have you bought, if like me then your half way to paying for water & you won't need to change with the socket ;)

Well the truth is I am going water as I am going Conroe and this rig is going into my office. Was thinking of getting this Swiftech H20-220 Apex Ultra+ Watercooling Kit (Socket 462/478/LGA775/754/939/940)
 
Gandalf, those graphs don't tell the whole story, your comparison is flawed as LAME will only use one core. Now compare a X2 3800+ that is running at 2.0 per core and you will see that it will get spanked core for core, however, you still have another core to play with to do something else. To put that in perscective, I used to have a 3700+ SD in this system, clocked at 2.8, thottled down to 2.65.

I now have 2 2.65 cores to play with (as my 4800+ is now at 2.65 per core), so you see, I could run two instances of LAME, with no effort.

Your comparison is with a 2.2 SD against a 2.00 X2, ofcourse it will lose, its 10% light on cycles.

Try doing that with your 3700+ SD.

;)


BTW as I'm typing this I'm trying to squeeze out some more cycles out of this rig, Im writing this as I have both cores running maximum through GO using large FTT's, plus various temp and monitoring apps, plus listening to tunes through WMP10, both cores running at 2.675.

Don't get me wrong mate, my stable 2.8 clocked SD would spank my X2 running single core benchies like SuperPi, but alas that is not the point.

I didnt do the benchmarks.

I have other things to do than squeeze more cycles out... lol


"So i saved the money and bought a A64 3700+, which are known overclockers"

Okaaaaay.
