| More G.Skill 2GB HV results :) Here is another testreport of this 2 GB Dual Channel DDR500 Kit: G.Skill 2GBHV F1-4000BIU2-2GBHV Specs: * Package : 2048MB kit (2x1GB) dual channel pack * CAS Latency : 3-3-2-8 (PC4000) * Test Voltage : 2.6~2.8 V * PCB Board : 6 Layers PCB * Speed : DDR 500MHz (PC4000) * Voltage : 2.6 V - 2.8 V * IC's : Infineon CE-5 $259.00 ($219.00 after $40.00 Mail-In Rebate) @ Newegg I have tried to finetune this memory to the max. But advanced memory tweaks did not seem to have a positive influence. Facts about 2GB HV: - This memory is a competer. It will show all its power until you reach its max stable overclock, you will directly see this (no boot/3derrors). - 3D apps (like 3dmark) are a better test for stability then Superpi32M for this memory. - Systemconfigs with ATI cards will get black screens (and VPU recover/ Directx errors) in 3d when the memory is generating errors. - Systemconfigs with NVIDIA Cards will show artifacts 3d applications. - TRFC (row refresh cycle time) has to be at least 14 to get the best result. - Loosening the TRCD and TRP timings don't seem to have any influence in overclockability. - This memory will slightly react (1 or 2 Mhz) on increasing the VDIMM (2.80V seems to be its hotspot here). - Changing advanced memory timings will not lead to a higher overclock. - Command per clockcycle disabled (2T Timings) doesn't give any boost. - A little airflow over the memory improves its stability (after I turned of the memfan, 3dmark failed). A 3000 RPM fan will not result in higher clocks then 1000 RPM. TEST SYSTEM This is the same system I have used for this review: http://www.madshrimps.be/?action=getarticle&articID=350 PSU: Tagan 480W U1 Mobo: DFI Lanparty NF4 Ultra-D, bios 3-29 CPU: AMD Opteron 146 VGA: ATI X850pro @ XTPE HD: 2x WD 1200JB Sata2 @ Raid0 OS: Windows XP x64 UK Coolsetup: Watercooling @ CPU/VGA (nexXxos Hp pro/alphacool 900 pump/ evo 360 rad) NB47J @ nf4 + low RPM fan Low RMP ledfan @ memory SOME RESULTS Memtest+ 1.65 3dMark 2005 v1.20 SuperpiMod (tested with 16M/32M, only screens with 16M) Default Timings: CL3.0-3-2-* 1t, 3D/Superpi/Memtest Stable 258Mhz CL3.0-3-2-7 1t [Memtest] CL2.5-3-2-* 1t, 3D/Superpi/Memtest Stable 239 Mhz CL2.5-3-2-5 1t [Memtest] CL2.0-3-2-* 1t, 3D/Superpi/Memtest Stable 216Mhz CL2.0-3-2-5 1t [Memtest] Prime Conclusion: At this moment, this is the best 2GB DDR1 kit which G.Skill has to offer. It's specifications are very good. Overclock results are also good. Compared to some other 2GBHV / Infineon CE-5 based memory kits, there is not so much headroom above these specifications (8 MHz). But, just like every memory/cpu/gpu , luck is a big keyword. |

At 2.5-3-3-*, 2.5-3-2-* or 2.5-4-4-*, it all reached 239 MHz as max stable clock. | |
