Drives for high PCIE frequency?

[Patch]

Suggestions? (Aside from IDE. No ports.)

All the projects I'm currently working on benefit from (or must have have) PCIE of 125+.

My current drives limit me to 115 or less.

Velociraptors and SSDs :D
BUT you need to be sure that your vga can handle this pci freq ;)

[Patch]

Thx for response Sofos.

My Vrap is currently the problem. Used to do better, but lately not handling more than 115. Tried 2 different VGA's so far.....maybe try another tomorrow.

Haven't tried the OCZ vertex yet because I'm not benching what it's tuned for..... guess I should just slap it on to see before buying more drives.

IDE is for high pci freq for sure . If you want to bench 3dmark2001 SE then the most appropriate HDD is an IDE . Aside from IDE you can use the other controller of your motherboard, pci should go a little higher I guess .
130Mhz on pci is what you are looking for .

vertex2 does 130 and then shits a brick on the R3E for me :) vga is 8500gt 512mb this was with 920.

Like sofos said you can use the marvell ports etc

PS it was still scaling with pci-e at 130 :0

I guess this will be my next hurdle. I am ignorant in the ways of pci...I have never benched with anything over 104. (Needs schooling) ;)

all three of my 160gb Raptors handle 130-135 PCIE in the Intel RAID controller.

Yeah, I'll revisit 3D01 next time with different RAM and an IDE drive.

Right now I'm just trying to push a 920. Boots and benches at 239X21 under SS without a hiccup - but can't do 240 baseclock AT ALL. I've seen that kind of wall before.....and it's PCIE limited baseclock for sure.

Didn't think of trying a different port, doh! I've done 120+ PCIE before with this very drive..

[ReverendMaynard]

any of my 240+ bclck benches were done between 116 and 119mhz PCIE, just when trying to high validate over 250 did I need 130ish.

I may have my bios settings somewhere if you'd like to reference. With a 760 Classy though.

patch you on r3e? if so you need to use slow mode over 4000qpi link speed

For real? How does that impact performance?

[Patch]

I was stuck at PCIE 113 last night, and it didn't like that very much - would occasionally drop things and not open aps until I dropped it to 112.

Not gonna waste LN2 until I'm only limited by temps/voltage.

Only reason I bought this chip was for some 2D bointage and a max validation. :D

no difference in 2d but 3d 06 and vantage cpu test are total fail. Good thing we dont use these for 3d though :thumbdown:


PS patch, some cards dont like to be at a certain range of pci-e so you can always try higher than where you failed as well. IE 113 fails try 120 etc

[Patch]

Just saw the slow mode tip, Splave. I've always avoided it because I'm usually doing 3D.


Lots of things to try here.

[Neuromancer]

Slow mode failed for me on 2D on the classified(5-6 seconds loss in 8M)... w00t.. this might be good news for ASUS 2d benches though :)

Just the thread I was looking for.:thumbsup:
