FX530 Memory Performance Upgrade and Timings in BIOS
I replaced all my FX530 memory with 4GB (4x1GB) of Patriot Extreme
Performance DDR2 Bladed Series 667MHz PC2-5300 memory. This memory features low latency CL of 4, heat shields, can be overclocked, and has a lifetime warranty. The price is good at NewEgg at $24.99 per 2GB kit. I would have rather gotten a 2x2GB kit but NewEgg doesn't have it yet but I did write them to suggest they do stock it. The part number for the 2x1GB kit is PDC22G5300LLK. The part number for the 2x2GB kit is PDC24G5300LLK. I think the 800MHz version would work too but it would auto-clock down to 667MHz which is the maximum memory slot speed the FX530 OEMD975XBGG1 motherboard supports. With my original Samsung 2GB memory and Kingston 2GB memory that I added to it. My Auto memory timings at 667MHz were 5-5-5-15 and Auto voltage of 1.8V in BIOS under Performance/Memory. My Windows Vista Experience Index for memory was 5.4 with 4GB of regular 667MHz memory installed. With the Patriot memory, I'm using 667Mhz 4-5-5-15 timings at 1.8V. The memory is actually rated as low as 4-4-4-12 at 1.8V but in my system that proved unstable at those low latency settings so I had to change it somewhat. When you first install this Patriot memory, the BIOS will use auto detect settings of 5-5-5-15 just like the old slower memory. So change it to Manual settings of 4-5-5-15 at 1.8V. It has been running very stable on my (Intel Core 2 Quad Q6600 CPU) system at those settings. I experimented with different timings, voltages, and frequencies but I can't get any better performance than with those settings. My Windows Vista Experience Index for memory improved to 5.5 with 4GB installed. For testing I ran Super PI 1M tests, Prime95 blend CPU/Memory stress testing, and Futuremark's 3DMark06 benchmarking utility. I also used Windows Vista's Memory Diagnostics Tool (under Start Menu/Admistrative Tools or from the Search bar) just to verify that i didn't have any defective modules installed. In case you are wondering about the timing numbers, the first and last numbers are the most important. The first tCL number (I'm using a value of 4) is for low CAS Latency and is the most important for memory performance. The last tRAS number (I'm using a value of 15) is for higher stability and doesn't affect performance. The second tRCD number in combination with the tCL also affects performance. I had wanted to make this number 4 too but it was unstable and failed a memory stress test so i had to make it 5 instead. But at least I did get a performance gain over using the regular DDR2 667MHz memory. I think the FX530 with the 1066MHz Front Side Bus (FSB) can't handle any lower latencies than what I ended up with. But I'm curious to know what those lucky CPU/FSB overclocked FX530 owners get out of their memory timings though. The worst part about my FX530 is having those BIOS performance settings locked out, because if i could adjust the FSB and CPU I could probably take full advantage of this Patriot memory and maybe would be able run it at 4-4-4-12 or 4-4-4-15 and still be stable if I could only get a 1:1 FSB to DRAM ratio. By the way, I also tried changing the memory frequency to 800MHz to do a pure memory overclock which worked at 5-5-5-15 and 2.1V but when I tried just changing the first tCL value down to 4 and rebooted all I got was 3 beeps and a non-booting system! Luckily the BIOS maintenance mode jumper position allowed me to fix it so I just changed it back to 667MHz 4-5-5-15 at 1.8V since that seems the sweet spot for me. To those lucky CPU overclocked FX530 owners, do you know what makes your BIOS unlocked to get to your CPU and FSB performance settings? Do you use a different version BIOS than the rest of us or is your OEM motheboard different? Plese check your motherboard part number with the free CPU-Z utility and BIOS version and let us know!

Ben Update - I don't know why but I decided to try this memory only BIOS overclock from 667mhz to 800mhz with the timings 5-5-5-15 again, but this time at 1.9v instead of the 2.1v that I tired before. Well My Windows Vista Experience Index for memory jumped from 5.5 to 5.6 so I'd say there was some kind of memory bandwidth improvement this time! The slightly lower voltage amount had some positive effect. Here is my online shared Experience Index 5.6 Results page at http://www.shareyourscore.com/MyScore.aspx?scoreid=8158 Keep in mind with 4gb RAM before I installed Patriot memory my Index score was only 5.4 out of a possible 5.9 score. So scoring a 5.6 is a big jump in performance. I'm almost afraid to run a Prime95 blend stress test but I will. There is some debate how important this is to worry about unless you are making important scientific calculations to save the Earth from a possible Asteriod strike My Super PI 1M time is 21.953 so far. The more times I run this test depending on what my PC is doing, I usually get lower times calculating PI to one million places. I haven't run new 3DMark06 tests yet either, but you can run 3 tests in a row and get wildly fluctuating results. Steve |
