clipperjay Posted March 22, 2005 Share Posted March 22, 2005 My spec's as follows: Shuttle SB95PV2 FSB 800 MHz, Phonix Technologies LTD i925X Corsair XMS Pro Twin 1GB PC5400 P4 570J SD-3.8GHz overclocked to 3.96GHz Hello I'm trying to match my speeds from my PC using old Rambus as these suckers cost more than my old 1GB 40ns PC800.! My new computer is great for encoding but day to day it's like a Bentley she eats too much power and she plods.! I have done the following to trim her up a bit, but would like a profesional opinion on what I have done wrong.?

Corsair Employees RAM GUY Posted March 23, 2005 Corsair Employees Share Posted March 23, 2005 Jay I do not understand what you are trying to get here; you are already exceeding RDRAM speeds. Maximum Bus Bandwidth: 6592MB/s (estimated) And what are the un-buffered results and you might try Everest to run the bench mark it’s a bit more easy to read and consistent. And please tell me the exact bios settings you have set and the CPU speed you have installed. Link to comment Share on other sites More sharing options...

And please tell me the exact bios settings you have set and the CPU speed you have installed. Ram Dude The main reason for this thread is that I found Rambus is quicker and thought DDR2 could give me better performance? I'll re-phase that one, more smooth and stable. My average temps are coming upto 55C MAX 62C with downloading programs on and nothing else.! Trying to make the Ram as effiecient so I can turn down FSB down abit.! wouldn't even boot at times of 3-3-3-8 but stable at 3.4-4-4-11 I've had it at 3.4-4-4-6 with FSB at 207MHz killed bench mark's on every test but started to over heat.!!! I'm just trying to make the efficiency better, but not sure what balance for the Bios is a good combination?

Corsair Employees RAM GUY Posted March 24, 2005 Corsair Employees Share Posted March 24, 2005 I would set the Dim Voltage to 2.0 Volts and set the timings to Cass 4-4-4-12 with the memory frequency set to 533 MHz and try to over clock you CPU a bit more and see where it tops out. Probably arround 230-245 Mhz with this MB. Link to comment Share on other sites More sharing options...

clipperjay Posted March 25, 2005 Author Share Posted March 25, 2005 As long as your system is stable I would stay where you are then. Thanks Ram dude for all the help the voltage seems to have done the trick making it very stable. 87ns still slower than my rambus, but will get better cooling for the P4. This Ram does perform will have to wait until dual core processors come out and find how she reacts to them.!! :laughing: Jay. Link to comment Share on other sites More sharing options...
clipperjay Posted March 28, 2005 Author Share Posted March 28, 2005 Ram dude just to let you know I have improved the figures below but had to turn off the 533MHz to auto mode in bios. This improves the sync between CPU and RAM I think? Update 3-3-3-8 Everest Read 5725 Write 2286 Laytency 86.5 Can't improve the Laytency without reducing the other RAS and CAS.? The best Laytency was on 3-3-3-6 But Read 5580 Write 2280 Lay 84ns. Any sugestions.? Jay Link to comment Share on other sites More sharing options...
clipperjay Posted June 8, 2005 Author Share Posted June 8, 2005 Ram guy from my previous posts can you tell me where do I start to change the ratio between FSB and RAM without changing the 4-4-4-12 or 4-5-5-15 for 675-772 MHz on the Ram I have. I realise that the divider can sort out the 3:4 currently on my set up but if correctly noticed there is only 400MHz or 533 and auto in the Bios. Where else would I change a ratio to 5:4 or 1:1? I'm starting to understand that P4's need loads of bandwidth to operate efficiently and tightning the timmings will not give me joy. Your help in this is much appreciated. :D: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted June 8, 2005 Corsair Employees Share Posted June 8, 2005 You should set the memory Freq at 533 MHz and then lower the CPU multiplier and over clock your CPU, but this MB and or system is not known to be a over clockable MB so you may not have all of these options.
