126304 2003-03-09 03:33:00 Ok that is some really slow ram, i had a look on sandra, and the speed your getting equates to using PC100 SD Ram on a BUS of 133

For examply my PC using DDR2700 is going at around 1700Mbps

Go through the tests that sandra has, and find out as much info as you can, you will see that you can compare against similar systems, do so. Don't worry if your computer is 10% behind what a similar system has been recorded at, but if you find considerable differences then alert us.

I'm starting to think that your Front Side BUS (FSB) has been set wrong.

126305 2003-03-09 03:49:00 Hi

Could be wrong here but, Array Memory Used shows 256MB ram in your Original post you say you have 512MB ram. How many individual sticks of ram do you have? SiSoft should give results on MBs and slots filled in first couple of modules, if memory serves :8|

126306 2003-03-09 07:01:00 Not too sure about that . . . I remember reading something somewhere whilst benchmarking that said my FSB could be wrong . . .

I have 1x 512MB PC2100 stick of 'Nanya' RAM . . .

Could this mean that Sandra was only benchmarking half my RAM?? That wouldnt result in half the speed tho, would it?

I was under the impression that my board supported my CPU's 266 MHz FSB, but I may have been wrong . . this mobo was an impulse buy at the time - it has some interesting features . . .

(I'm sure my Athlon XP 2200+ has a 266 FSB . . . )

If you could direct me to a newer version of Sandra, that would be helpful as this one's top 'Reference CPU' is a Pentium 1 . 6 or Athlon 1 . 33 gig - no Athlon XP's at all . . . . .

How can I find out what my FSB currently is?? The BIOS?? What about all those multipliers etc?? Perhaps I just havnt set this up right . . .

I built the machine myself - I've been into this since my 486 DX4/100 I had about 10 years ago (ish)

Hell I was programming my Commodore 64 when I was 4 years old - surely this should be simple . . .

126307 2003-03-09 07:02:00 Just out of interest - is there anybody out there with the same (or similar) system with the same (or similar) RAM that could do a quick benchmark for me so we can have something to compare with?? BR41NZ (3307)
126308 2003-03-09 07:47:00 Just out of interest, I had a look at the manual. Is SW1 dipswitch have only switch 1 ON? ( there is a light (LED) by the dipswitch which should be on if this is the case). And is SW2 dipswitch set with switch 6 ON only? Pheonix (280)
126309 2003-03-09 07:50:00 My motherboard:

SL-75DRV5 (ATX)

* VIA Apollo KT333
* ABSII
* FSB 333/266/200MHz
* DDR333/266/200
* UATA-133
* Multiplier Setting
* BIOS FSB Setting
* Vcore Setting
* DIMM/AGP Voltage Setting

126310 2003-03-09 08:07:00 SW1 = All OFF including the LED
SW2 = 1-5 off, 6 on.

SW1 is saying that it's autodetecting the multiplier, and SW2 is saying the External Frequency Setting is set to :-

External Clock: 133.3MHz
PCI Clock: 33.3MHz
FSB Clock: 266MHz
BR41NZ (3307)
126311 2003-03-09 08:11:00 I'm not sure if I could set it manually and have it very close... it's hard to make 1.8GHz when the max multiplier is 12.5

This would mean I would need the external clock to be 144.

There is an option of this:

External Clock: 140MHz
PCI: 35MHz
FSB: 280MHz

But I'm not too keen on frying my motherboard...

Question:- Why oh why is there not a decent setup to keep the PCI Bus at 33 and the FSB at 266 whilst multiplying the External clock to 1.8GHz????????

126312 2003-03-09 08:19:00 I wonder if I could be classed as over-active in my first PressF1 posting attempt . . . . . . . . . .

When I bought my RAM I also bought a Thermaltake Active RAM Cooler and stuck it on . . . nice wee fan . . .

Out of interest, would this in any way cause the RAM to become faulty? Or something along those lines??
