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?

Did XP auto-detect the CPU and update the kernal to multiprocessor? I have recently upgraded from a 3500+ to a 4600+ X2 and I had to re-install XP to get the multiprocessor kernal. Sandra benchmarks are multi-threaded and therefore will use the second core but XP will not unless the kernal is updated.

No I mean the driver.

It looks like you need to install the driver mate.

If you ctrl-alt-del, go to the performance tab, you should have 2 (not 1) graph in the CPU usage history.
 
Good post,
i got a 4800+ last week and also wasn't impressed with speeds. Have just installed AMD drivers and optimizer. Don't really want to install XP again.
 
The AMD driver is just to enable CnQ. The most important requirement is the multiprocessor kernal. Without this you are running single core. To check look under 'Computer' in device manager. It must say 'ACPI Mulitprocessor PC'. If not then it's a re-install of XP I'm afraid.
 
You don't necessarily need to reinstall XP if it doesn't show 'ACPI Multiprocessor PC'.

Within Device Manager, expand on computer, right click on 'ACPI Singleprocessor PC' and then click on update driver.

Don't let windows search but choose install from a list or specific location. Again, don't let windows search, and you should see a list of options. Select 'ACPI Multiprocessor PC', and then click Next and follow the instructions.

After a reboot, it should be running in Multiprocessor mode.

If it's already setup for Multiprocessor PC, and you've got the optimizers installed, and checked they are there in the registry, then I'm not sure what's wrong with it.

I would probably after all that proceed with a fresh install, with a copy of XP that has SP2 included.
 
I went from an FX-55 @2800Ghz to a 4800 X2 @2400 and the X2 was just as quick as the FX in games i didn't seem to loose any fps at all.Anyway the X2 is now running at 3000Ghz under Vapo and i still can't see much difference.
 
the fact is most games and apps will not utilise dual core yet

this is why i am holding of going dual core once a game that i play a lot starts using it i will reconsider

the only reason i can see now is if you multitask a lot video encoding and stuff

but cant say i could justify a 100 notes + as i dont multitask that much
 
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.

Ok, well i have the same chip and agree there is not a huge difference.

However, i can easily ctrl-alt-del out of a game, leaving it running, and check email/surf without either activity lagging.

That is what dual core does for me - I agree, it is not earth-shattering.
