New rig's network speed greatly reduced.

[Schadenfroh]

Well, i have sevarl computers at my house. I normally get around 300k downloads.

New rig

Gigabyte K8NS-ultra 939 (nforce 3 ultra)
Athlon 64 3000+ 939 (Venice)

those are the only things that i upgraded from my old rig, before that i had not had any bandwidth issues.

What i did.

1. When i first got it in, i formated and installed windows xp 64-bit edition (oem from new egg). I installed all the drivers from nvidia (nforce drivers for xp64, etc.)
2. I saw my download speeds were only around 70K, figured my isp was giving me trouble, untill i downloaded the file on another computer, it downloaded it at 300K.

3. So i ran somebandwidth tests on both...... The new rig was 1/3 of the speed as the other computer (bandwidth that is).

4. I then switched out NICs (there are two eithernet ports on this mobo)

5. rebooted, ran the banwidth tests again, the results were identical

6. Disabled other NIC in the device manager, reran the tests, tests identical

7. I then concluded that it was the POS driver support for XP 64 that was causing this, so i formatted again and put win 2k on it and installed the latest WHQL drivers from nvidia for nforce.

8. Ran tests again, results were identical as before....

9. I dug up a 10/100 NIC card out of the closet, put it into the PC, and ran the tests again.... results identical as before.

10. I then concluded that it could possibly be the actuall LAN wiring giving me trouble, so i brought the computer downstairs, unhooked the pc that was getting normal download speed and was scoring normal on the bandwidth tests and hooked the new rig into it.

11. I then tried it in every NIC port and the results were identical, around 70K downloads and the bandwidth tests showing it to be 1/3 of the speed as the computer that was previously hooked up.

I am now out of ideas..... Is the onboard nvidia firewall to blame, eventhough i am now using a seperate PCI 10/100 NIC that should not be effected by it or is this something wrong with the motherboard?

note also that while i was doing the tests and downloading, i had turned all PCs in the house off to prevent an IP conflict.

thanks... I hope my motherboard is not shot.

Are all your tests being run from the same second PC? Or are you testing from various PCs and through various ports on your switch? If no, then that's my suggestion.

EDIT: You also mentioned in your description that you disable network cards, which I assume means you did it in Windows. You may want to try disabling all the network cards in the BIOS then adding a known good PCI nic and see how that performs.

EDIT2: I may be confused a little, but it sounds like you are saying you get 1/3 the performance when downloading off the internet. If that's the case, then it could be your cable or dsl modem. Or maybe even something with the wiring outside of your home that is completely out of your control. Make sure you do all your tests in-house, from one PC to another, and then see how it does.

i have tried plugging it into 3 differant ports on the router.

Are all your tests being run from the same second PC?

Yes and also a third one, the 2nd and 3rd pcs produced the same results as the original pc did before the format, they all get around 300k downloads and perform the same on the bandwidth tests, just as my old pc did before the new install. The new rig is about 1/3 the speed of the two.

Or are you testing from various PCs and through various ports on your switch?

also doing this, i have plugged the new rig into the same either net cable as the ones that are working properly, it produces 1/3 the bandwidth of the others.

Yes

You may want to try disabling all the network cards in the BIOS then adding a known good PCI nic and see how that performs.

Will try the first part, but i have already tried it with a known good nic and it also performs 1/3 of as well.

I may be confused a little, but it sounds like you are saying you get 1/3 the performance when downloading off the internet. If that's the case, then it could be your cable or dsl modem. Or maybe even something with the wiring outside of your home that is completely out of your control.

Well, if that were the case, the other computers would be slowed also, they perform fine.

thanks for the input

Did you have any registry tweaks or speed tweaks under your old setup?

That's a strange problem.

What else is on the pci bus? Try removing anything from the pci bus as if I remember correctly most onboard nic's are still on the pci bus. Does nforce 3 have the firewall like nf4? If so, then it could be something wonky with that, try a bios flash. Well I'd try a bios flash anyway.

Nothing was on the PCI bus, save the 2nd nic i added and then removed when i found that it had identical performance. Yes, the nforce 3 has a built in firewall but i cannot find a way to disable it in the bios and i have tried it with both the firewall disabled in the drivers in windows and without the software for it installed all together. I am running the latest official bios for the motherboard, which is the only version that i believe works with the cpu i have.

Nope, and none on the other 2 that i have tested the current one against.



Is it possible since the NICs on the mobo are probably on the pci bus that the pci bus is somehow damaged?

 

[Schadenfroh]

just tried it with another macronix nic with all the integrated networking stuff disabled.......

got identical results.


I also stuck linux on it, ran it, identical results.


Think the PCI bus is damaged?

Possible, you should be able to find a tool that will check what level of data bandwidth your pci bus can handle. Therefore it it says like 60kb/s ur screwed. How long ago did u buy it and from who?

3 days ago from newegg, came sealed from the factory. Where can i get a tool the pci bus?

Well I just quickly looked for one and don't see one, except a card for 189 bucks lol. What you could try is a pci vid card. If I remember correctly there are some bench marks that just bench the card it's self? Try the pci vid in 2 systems and compare results. Otherwise, I have no Idea how to check, I;d just get it exchanged. Sorry!
