Yo XS Bandwidth Freaks!
Welcome to yet another episode of OCing Reports! Few days ago I got the package from G.Skill USA with their new 2GB set - F1-4000BIU2-2GBHV which has rated speed of DDR500 8-2-3-3.0-1T. This set is built with Infineon CE-5 DRAM components. By lifting heatspreader a tiny little bit I managed to see the markings to confirm that as well as IC weekcode of 0550. As usual, modules are built on Brainpower B6U808.
This write-up is intended to show what this new product may be capable of. I have seen few other members posting results with this set in XB section, including CapFTP G.S EUTech and quent. So, you will have some basic idea about the product already, even though all sets were provided directly by G.Skill. Initial and very small shipment of those have been sold out at Newegg but I was told there's more on the way from G.Skill USA warehouse.
I will be testing stability with SuperPi 32M, Memtest for Windows, SP2004. As we already know, 3D testing seems to be mandatory for Infineon-based modules, therefore I will also run 3DMark2003 and play NFS:MW as well as FarCry.
Setup:
Opteron 146
DFI NF4 Ultra-D, BIOS release 11/14/2005
EVGA 7800GTX 256MB KO @ 540/1400 ForceWare 81.98 & 84.21
Let's get going...
Part1: ALL-STABLE, including 3D benchmarking and 1hr of gaming
SPi32M & 3DMark2003 @ 300x10=3000Mhz DDR500 5-2-3-3.0-1T
SPi32M & 3DMark2003 @ 306x10=3060Mhz DDR510 5-2-3-3.0-1T
SPi32M & 3DMark2003 @ 309x10=3090Mhz DDR514 5-2-3-3.0-1T
2hrs of SP2004 LargeFFT @ 309x10=3090Mhz DDR514 5-2-3-3.0-1T
~600% of Memtest for Windows @ 309x10=3090Mhz DDR514 5-2-3-3.0-1T
SPi32M & 3DMark2003 @ 312x10=3120Mhz DDR520 5-2-3-3.0-1T
~600% of Memtest for Windows @ 312x10=3120Mhz DDR520 5-2-3-3.0-1T
The maximum fully-stable OC I managed to achieve seems to be 260MHz and is is pretty much the same as other revied kits did. I could reliably play both games without any halts, freezes or artifacting. As soon as I raised to 261MHz, lockups started with looping sound, etc. More voltage (up to 2.9v) did not ease the situation. Findling with latencies and other DRAM settings in BIOS did not help either. In other words, I got typical symptoms that I have experienced in the past with other Infineon modules (Corsair's PC4400PRO, OCZ's EB PC4000 and GSkill's PC3200ZX) where past certain speed (vary for different sets) system looses 3D stability.
I also run some test at CAS2.5. To my surprise, it was absolutely neccesary to bump voltage to 2.94v (2.98v with DMM) to achieve stability at DDR500. Without this, system refused to boot to Windows no matter what DRAM settings were used. But once there, I managed to run a full set of my stability tests:
SPi32M & 3DMark2003 @ 288x10=2880Mhz DDR480 5-2-3-2.5-1T
SPi32M & 3DMark2003 @ 300x10=3000Mhz DDR500 5-2-3-2.5-1T
2hrs of SP2004 LargeFFT @ 300x10=3000Mhz DDR500 5-2-3-2.5-1T
~600% of Memtest for Windows @ 300x10=3000Mhz DDR500 5-2-3-2.5-1T
A small update with CAS2.0 results. I spent about 30mins trying to get div150 working with CAS2.0 (no problem with 2.5 or 3.0) but for some reason it would just not boot to Windows. I will try again later but for now I decided to drop HTT a bit and go with div166.
SPi32M & 3DMark2003 @ 264x10=2640Mhz DDR440 5-2-3-2.0-1T
2hrs of SP2004 LargeFFT @ 264x10=2640Mhz DDR440 5-2-3-2.0-1T
~600% of Memtest for Windows @ 264x10=2640Mhz DDR440 5-2-3-2.0-1T
Part2: Desktop stable only
SPi32M @ 318x10=3180Mhz DDR530 5-2-3-3.0-1T
SPi32M @ 322x10=3220Mhz DDR536 5-2-3-3.0-1T
2hrs of SP2004 LargeFFT @ 322x10=3220Mhz DDR536 5-2-3-3.0-1T
~600% of Memtest for Windows @ 322x10=3220Mhz DDR536 5-2-3-3.0-1T
Part3: Ehhh... My conlcusion
Well, there you go! G.Skill finally released DDR500 rated Infineon based 2GB kit. After PC3200ZX and PC3200HX, it was about time to do some higher binning. I was hoping for a bit more headroom in 3D testing, but DDR520 is still very satisfying. I'm very interested to see how the rest of the 2GBHV supply is doing. So, go get one and report back here, OK?
I will try to answer any questions regarding above results. Fire at will!
Thanks for showing interest in this OCing Report
