Memory speed...

[gyoung]

I have a Abit KT7 motherboard which allows you to tweak the memory. I have 128MB PC100 stick of generic memory. I've looked at it and I can't find any information about the manufacturer.

I've tweaked just about everything. I'm using these settings:
HCLK+PCICLK (for PC133 RAM)
Enhance Chip Performance = Enabled
Force 4-way interleave = Enabled
Enable DRAM 4k-Page Mode = Enabled
Bank x/y DRAM Timing = Turbo
DRAM Bank Interleave = 4-Way
Delay DRAM Read Latch = Auto
MD Driving Strength = HI
SDRAM Cycle length = 2 for CAS 2 PC133 SDRAM
Fast R-W Turn Around = Enabled

Here's my question. Should a generic piece of memory be able to do this? The memory came in a computer I bought in May 1999 off of ebay. Does this mean the memory is running at 133 CAS 2? I am not experiencing any problems. Games aren't locking up or anything. Sandra showed big improvements in memory benchmarks. When I get home I'll share the numbers with you.

My understanding of the matter is that a select number of chip makers make all the RAM chips. So if your generic RAM has good chips, then your RAM will be really good. Otherwise, if you're experiencing no problems, I say more power to you and your comp!

Szech,

You are correct. 100Mhz is the labeled freq. It has gots to run stable at this freq to be sold as 100Mhz. Most RAM and some other device are manufactured to perform beyond their labeled freq, but vendors don't want to chance having to support these higher numbers.

In english.
100 100mhz RAM>>>> 100 have to run stable at 100Mz.
Of those 100, 98 run stable at 133Mhz. Vendor will never sell as 133Mhz as those 2 that fail will cuase more grief than the gain from the 98 that will.

Much like OCing procs. Many run procs at higher frequency than labeled for years without probs.
