A performance issue
I have come into possession of a 64MB PC100 DRAM. My computer currently has
128MB PC133 DRAM. Running W98SE. Can I run both DRAMS at 100MZ without damaging anything? If I can't will I see a performance boost or degradation by setting the bus to 100MZ and running both DRAMS? Thanks, Dan Hacker -- ---------------------------------------------------------------------------- --- Madness takes its toll.

Your processor [speed and type] and motherboard [model and BIOS or at least the computer manufacturer and model] along with the actual attempted memory manufacturer and IDs are necessary. Pending that information: The general recommendation is to not mix speeds /CAS of memory IF any chips are made within the last three [to five] years without first checking to see if they can support different clock speeds and at what CAS/RAS they support that speed. Likely you may not be able to lower your present FSB [front side bus speed] due to your processor requirements unless you have a split/dual bus configuration [not likely] though you may be able to downgrade your processor through the BIOS, though that would defeat the purpose. You MAY however, be able to overclock [per the module rating] the 100 to 133 if we are supplied with the information. Please post your information so we can help determine your potentials. -- MEB http://peoplescounsel.orgfree.com/ BLOG - http://peoplescounsel.spaces.live.com/ Public Notice or the "real world" http://groups.google.com/group/the-peoples-law?hl=en - discussion group for general aspects of Law verses the Peoples' of the world "Most people, sometime in their lives, stumble across truth.

A performance issue
Yes, you can usually do that.
However, why don't you try it and see if the performance really does increase. Some motherboards do not work well with a processor (cpu) running at a different freq than the DRAM. ie: cpu on a 133MHz FSB and the SDRAM on a 100MHz FSB. With ram so cheap, why not just buy what your motherboard mfg recommends? PS: If you have to set your cpu FSB to 100MHz to use the ram, your performance will be noticeably worse.

If your PC100 DRAM is high quality, it may run just fine at 133MHz.
Mine did. PS: I used it in combo with a stick of PC133 DRAM. "Rubyjack" wrote in message ... I have come into possession of a 64MB PC100 DRAM. My computer currently has 128MB PC133 DRAM.

I may be wrong, but I was told if you mix speeds, you were automatically
limited to the slowest speed. I'm mixing 133 and 100, and what is more important to me is the added memory, not the speed. I don't believe one could actually see the difference between 100MHz and 133MHz, but the additional memory, yes. The biggest consideration in my opinion, is whether or not the mis-matched memory will "play well" together.

Thanks, Dan Hacker Can your motherboard/chipset cache more than 128MB of RAM? If not, then you may actually experience a slowdown when you add your 64MB stick, even if you can get it to run at PC133 speeds. - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

A performance issue
Not really true if you set the FSB speed to 133MHz for the ram.
If you let the system do it automatically, it will usually revert to the speed of the slowest ram stick. Some of the high quality 100MHz ram will easily run at 133MHz or higher. Generally, mixing ram speeds and sometimes even CAS rating and brands is not recommended for optimal success. However, if he wants to try it, then he will have the answer. If it gets into a non-boot scenerio, usually just removing the slower stick will correct the problem. If it does not and he cannot get into the BIOS to set the ram speed manually, he will have to shut down and clear the BIOS using the 'jumper' to clear it and then reboot. If he has to run his cpu at the slower 100MHz FSB also, he will be slower, even with the addition of more memory. PS: running the memory at 133MHz or 100MHz would not show a major difference in his system. The cpu FSB speed is much more important in terms of performance improvement.

As memory manufacturers became more productive at module creation, and specific processor/mother boards began to require specific and limited modules; the ability to use that memory in the old fashion of "trial and error" or reliance upon supposed new automatic BIOS recognition when mix/matching went the way of the dinosaur when attempting to deal with newer controller chips in a mixed environment. New module "controller chip" designs coupled with better QC apparently allowed the manufacturer to essentially lock the supported speeds and CAS/RAS available/or for which they could be used [Think Intel's better manufacturing and QC allowing them to lock processors. SEE NOTE * ]. Mixing those essentially locked modules, has been found to cause corruption issues. So the long held belief that CAS2 100 could easily replace or work with 133 CAS3 was/is no longer viable. Moreover, if CAS3 100 [which was/is the most prevalent produced] is attempted at 133 at ANY CAS/RAS, numerous issues pop-up. They may pass POST, but when actually used by the OS, the errors abound. The same has been found true, at times, with 133 CAS2 attempted at 100. All the major manufacturers openly supported, CAUTIONED, and specifically noted on their websites and in their adverti$ing, that one must carefully match the BIOS support, processor and the memory, as failing to do so, likely would cause failures. One can still find smaller manufacturers that create multi FSB/CAS support modules, though that's likely due to the controller chip they used, rather than any real intent. *This change over related directly with the Asian memory crash and burning of a memory chip manufacturing plant. The investors and the "BANKS" demanded updated manufacturing techniques from the survivors. Siemans apparently implemented this around the same time period. | | "Buffalo" wrote in message | . .. | If your PC100 DRAM is high quality, it may run just fine at 133MHz. | Mine did. | PS: I used it in combo with a stick of PC133 DRAM. | | "Rubyjack" wrote in message | ... | I have come into possession of a 64MB PC100 DRAM.
