Answer» Quote from: Computer_Commando on June 03, 2010, 04:57:00 PM OK. A science experiment! I don't BELIEVE it's a solvable problem. The motherboard that is supplied to Gateway has a very limited number of hardware variations. If you can determine make & model of motherboard, you may be able to FIND someone who has "hacked the BIOS" successfully. There is a chance that the mobo is supplied to SEVERAL manufacturers that each have their own BIOS. I have a computer in a similar situation but am not willing to flash the BIOS as an experiment.I will look for MB info and post it if I find it. I am beginning to think that I have a faulty CPU or motherboard that as you stated "is unsolvable".Quote from: cstitt on June 03, 2010, 05:10:31 PM I will look for MB info and post it if I find it.

It's performing just as it was designed to.Mother board is "Intel E210882" There is some other numbers on white labels also which is: 4000811 ABRG32847628 AA C29595-101 I don't know what the latter numbers are for!Quote from: cstitt on June 03, 2010, 06:25:24 PM Mother board is "Intel E210882"http://www.intel.com/support/motherboards/desktop/sb/cs-009009.htm Is this your motherboard? Your chipset P/N will identify which. 845GL or 865GV. http://downloadmirror.intel.com/15203/eng/D865GVHZ_ProductGuide01_English.pdf OR http://downloadmirror.intel.com/15212/eng/D845GLVA_ProductGuide_English.pdf Quote from: Computer_Commando on June 03, 2010, 06:32:15 PM http://www.intel.com/support/motherboards/desktop/sb/cs-009009.htmFinally caught on #845GE couldn't find info with AA# [recovering disk space - old attachment deleted by admin]cpu bus speeds celeron 400 MHz, p4 800 MHz, therefore P4 runs at HALF speed. Quote from: Salmon Trout on June 04, 2010, 12:10:03 AM cpu bus speeds celeron 400 MHz, p4 800 MHz, therefore P4 runs at half speed.We know. He wants to modify it, which is unlikely on a Gateway.From personal experience I can tell you that even if you achieve this (yes, it is possible on certain MB-CPU combinations), you will more than likely encouter intermittant issues with such things as USB, AGP, PCI Bus errors etc causing fatal errors and BSOD's. If its purely a 'science project' then have at it but be warned, you could invest a LOT of time getting the CPU running at the right speed, only to find its unusable. Thanks to Computer_Commando I was able to get the CPU's that are supported by MB from the manual which doesn't list 512/800. Below is the list: Table 2. Processors Supported by the Desktop Board Type Designation FSB Frequency L2 Cache Intel® Pentium® 4 processor 2.60, 2.50, 2.40, 2.20, 2A, 1.80A, and 1.60A GHz 400 MHz 512 KB Intel® Celeron® processor 2.20, 2.0, 1.80 and 1.70 GHz 400 MHz 128 KB If I can't get CPU to full speed would it be better with 512 cache at half speed or the 2.6 with 128 cache?Quote from: Sodde on June 04, 2010, 09:43:13 AM From personal experience I can tell you that even if you achieve this (yes, it is possible on certain MB-CPU combinations), you will more than likely encouter intermittant issues with such things as USB, AGP, PCI Bus errors etc causing fatal errors and BSOD's.Nothing is lost if things don't go right as I mention earlier I got the PC out of the throw away bin and it was trashed when I started puting it together. Nothing worked on it.A 2.6 Celeron at full speed is going to be MUCH faster than a P4 running at 1.3 GHz. Quote from: Salmon Trout on June 04, 2010, 12:33:18 PM A 2.6 Celeron at full speed is going to be MUCH faster than a P4 running at 1.3 GHz.Thank you, what difference does a 512 cache make as to a 128 cache CPU in performance? Quote from: cstitt on June 04, 2010, 01:24:30 PM Thank you, what difference does a 512 cache make as to a 128 cache CPU in performance? Not very much. And it would be completely swamped by the 50% speed reduction. |
