OCZ VX, Best Memory made since BH5!!

[viccyran]

I dont see what is the big deal with high HTT?? it's the FINAL hyper transport speed that matters for the overall performance of the system.

So with 390HTT, the LDT must either be 3x or 2x. With an LDT of 3, 3x390= 1170MHz, it is very unlikely since it's way above nvidia spec'd 1000MHz. So you most likely will use your LDT at 2X for 2x390HTT = 780 MHz, which is not a big accomplishment overall.

For memory overclock with 390HTT, you most likely will not be running your RAMs sync'd. (I have not seen anyone with 390MHz in memory overclock posted). So, the only ram options are to use 166 or 133 settings in the BIOS. With a 166 setting your memory speed would be 324 MHz (390HTT*166/200). Even that is highly unlikely, unless you go with the gskill 4800 sticks which only comes in 256 flavors for 2x256=512MB max).

So the most logical choice would be 133 memory setting in BIOS which is 390HTT*133/200 = 260MHz memory speed. I have seen people with much higher memory speeds than that!

So basically, running 390HTT is no big deal and is not such an impressive accomplishment in overclocking. It just sounds impressive on paper.

HTT isn't that important for A64, if you look at the benchmarks. The only reason high HTT is nice is because it gives people more options on how to run their chip at it's best

In addition, high HTT screens just look sweet.

[bachus_anonym]

basically, ability to achieve high HTT is for those people that are "multi-locked" (non FX owners)...
say you have e.g. 3200+ Winnie that's doing 2.8GHz. to get there at stock multi (x9) you need to run it at 311HTT... that's where high HTT is important....
even better, if you have 2.9Ghz Winnie 3200+ you need 322HTT... and so on...

that an sli board opp?

[esdee]

LDT = x ?

my guess is 3 but i would love to be wrong

/edit : when did you all answer!!?!?!

"Best Memory made since BH5"

so still not as good as BH5

why is everyone defending bh-5?
how often do you get 1gb dual kits of bh-5 thatll do 266mhz im @ 258 2-2-2-10 1T on my 754 260 was my best but it didnt last long.
this stuff is awesome.

If HTT isn't that important, what is?

[Tek]

If HTT isn't that important, what is?

The actual RAM speed itself and certain timings

[OPPAINTER]

...awaiting Oppainter's 400+ HTT screeny...

I never got one, tryed 400 and it wouldn't boot.

Guessing MSI comes with CoreCell utility? Asus right now feels a little barren and I have to test with ntune ATM. Where is the darned clockgen?
Have you tested TCCD with it?

I havn't used any utility, the board I got never came with a CD, no drivers, nothing

OPB tested TCCD on one of these boards.

Poor boy...poor boy...

Btw, nice board and HTT you got there.
Let's wait and see if the boards that will hit the market are so good or even better than that(/dream off...).

They better be better This board won't cut it, lack of V-core will be it's demise.

HTT doesnt mean anything. It's the final hyper transport speed that you get from HTT that's important. So, for HTT of 390 if you go with LDT of 2x then the final hypertransport speed is 2X390 = 780MHz.

The most important factor that affects system performance on an Athlon64 system is the MEMORY speed / MEMORY latency timings and FINAL CPU speed in MHz. To a lesser degree, the FINAL hyper transport frequency, but benchmarks have shown that there is very little difference between various hyper transport frequencies.

If HTT isn't that important, what is?

board's ability to hit very high HTT is needed only in one case:
say you have Winchester 3000+ which has default multi of x9.... if you have a feeling that your CPU will hit 2.7GHz then you would need 300HTT for it. but supposedly, you got phase change cooling and then thought that your Winnie could hit 3GHz... if your board can't achieve 333HTT then you're out of luck for that 3GHz.
apart from that, very high HTT just looks cool on screenshots but gives pretty much nothing in performance compartment.
what's important? CPU speed, actual DDR frequency and timmings.

or default 11x multi with people trying to go over 3ghz... that already went past what lot of memoy can do 1:1. 11x multi aren't quite the CPU I would call cheap yet.
Now that aside, glad it is working on NF4 boards.

[trans am]

ok, i owe an appology to everyone. my VX is doing much better on the DFI LP 754. Big thanks to acidbaby for telling me to set drive strength to auto LOL.
Settings on DFI:
drive strength auto
vcore: 1.425x123%
chipset voltage: 1.8v
AGP voltage: 1.7v
Vdimm: 3.41
2-2-2-10 1t command
all other mem setting on auto
heatspreaders are off with 90mm fan blowing directly over the ram
voltage for vdimm is done on modded dfi bios with the 3.3 pot turned up to 3.6v on the ocz PS 520w








HAPPY HOLIDAYS FROM TRANS AM

just for the record, this is the best memory I ever had!

[jinu117]

Woot! That's good. Too bad my A8N SLI doesn't have way to lock LDT multi for some strange reason...???? Works on ntune though...
Will play bit more to figure out but friggin ntune tops @ 250FSB. Where is the clockgen? :P On dos though I was able to test pair of bh-5 to 250mhz fine so I guess I will test my VXs all again. (3.36 memtest, 3.45 idle actual vdimm) I already modded the board for cap mod

[conrad.maranan]

DFI 754 owns! Like I said, I ran as high as 269MHz error-free on the same board. The next time I'm at my sister-in-law's place, I'm going to test higher.

Good job, Alvin! And Happy Holidays to everyone here at XS!

Appologies accepted Trams Am, lol!
Still, 33 seconds on SuperPi 1m isn't that great for a ClawHammer at 10x264 with those timings.
I did 33sec at 10x255 with my old Claw at 2-2-2-5.



10x264 should show 32 seconds i think.

Nice to hear the RAM works well for you at least.

He just needs to get in and use that A64 Tweaker now, or the DFI bios. Those timings displayed in his post aren't nearly as impressive as the clocks he's getting from the sticks. I understand that he is still just checking max mem clocks now though, all Auto, not optimised. That'd get him the missing second I bet.

Glad you are happy!

ya, id say i was happy with my VX too!!
(this is with a stock clocked x800xt-pe)



this PI was @ 265x11



all this with AIR cooling (and 2C outside air )
