REQ Info P800 Deluxe Memory / Configuration
Howdy -
I'm looking to invest in a P4 3 GHz chip and it looks like the ASUS P800 Deluxe is the mobo to go with. It's been awhile since I've overclocked a system -- (Pentium Pro days) -- so I need to know something about memory. In what I have read, the lower the memory latency, the better the performance at a given bus speed. The Kingston HyperX DDR400 (KHX3200/512) has a 2-2-2-6-1 rating (@ 400 MHz), which seems faster than the "recommended" Corsair CMX512-3500C2, which has a 2-3-3-7-T1 (?what is T1?) rating (@ 433 MHz). (Short version of this question: 400 MHz 2-2-2-6-1 seems like it would be faster than 433 MHz 2-3-3-7-1? Is this right? If not, why? Educate me!) I guess the essence of my question is that I want to maximize the performance, but the HyperX chip is not on the "approved" list in the ASUS literature. So... 1) WILL this HyperX chip work? 2) WOULD it be faster to go with the Corsair? Any help would be appreciated. Thanks! Strange Brewer |

Strange Brewer I have the kingston memory that you are reffering to and have it clocked at 2-2-2-5 with all of the performance stuff on. I have been very happy with it. Using the free version of Sisoft Sandra Max3 I score 5483/5481 with the memory bandwidth test. I have had no problems with stability or memory errors. I am running at these speeds with my 2.6GHz OC'd to 3.25GHz. I cant answer question 2 for sure, but to answer question 1 -- Yes, it will work very well. Hope this helps. ~Froggy |

They are supposedly matched pairs. Not sure if it makes alot if diff but
thats what I used. "Strange Brewer" wrote in message ... Thanks for the feedback jaeger - really appreciated. I guess two followup questions: 1) There is a 433 MHz HyperX KHX3500/512 with the same statistics as the Corsair -- any reason I shouldn't get the Kingston since it is a little cheaper? 2) Some of the vendors sell "2 packs" marketed as 1 GB, but if I buy the chips separate they are cheaper. Nothing special about the 2 packs right? (Yes, I'm planning to use the same memory chips in all 4 locations.) TIA- SB On Tue, 1 Jul 2003 22:51:23 -0700, jaeger wrote: In article , says...

Any compnay that adevertises "1T" operation as being better or faster is being misleading. Intel chipsets ONLY use 1T, so this applies to any RAM you'll put in there aside from non-compliant generic crap. (Short version of this question: 400 MHz 2-2-2-6-1 seems like it would be faster than 433 MHz 2-3-3-7-1? Is this right? If not, why? Educate me!) No. Go for the speed. You'll never notice lower latency unless you use a synthetic benchmark. Why is too long to explain in a ng post, but assuming you have a basic idea of how memory works-applications that are memory bandwidth intensive are generally the LEAST affected by lower latency. Because once the data starts streaming, latency has no impact. 1) WILL this HyperX chip work? Yes. 2) WOULD it be faster to go with the Corsair? No. |
