Bench Mark Scores

[DodgeViper]

Why are my memory bench marks so low?

[UnseenMenace]

Can you tell us a little more about the memory settings you are using

[DodgeViper]

Ok, I hope this is what your asking for. The Bios are my enemy.


Current FSB Freq. (266 Mhz)
Current Dram Freq. (266 Mhz)
Dram Clock (Host Clock)
Dram Timing (By SPD)
SDRAM CYCLE Length (2.5)
Bank Interleave (Disabled)
Precharge To Active (trp) 3T
Active to Precharge (tras) 6T
Active To CMD (trcd) 3T
DRAM Quene Depth (4 level)
DRAM Command Rate (1T) Command
DRR Voltage (2.70)

After trying 3 times to MEMORY bench mark my computer after making changes from CAS 2.5 to CAS 2.0 and changes to INTERLEAVE 4 I was able to post this score.

My computer was very unstable and i kept receiving this message,

An exception OE has occured at 0028:C0003E79 in VxD VMM (01) + 00002E79. This was called from 0028:00210016 in VxD

T-BIRD 1.4 @1530
CPU volts 1.89
+5.00v: 4.87v
+3.3v: 3.34v
+12.00v: 12.28
CPU VCORE +0.100V
CPU RATIO 10.0
DDR VOLTS 2.70
CPU CLOCK 153

your memory may not be able to handle those fast timings.

I just noticed that your 5V rail is running a bit low (4.87V). What kind of PSU do you have? That may be part of the problem.

Current FSB Freq. (266 Mhz)
Current Dram Freq. (266 Mhz)
Dram Clock (Host Clock)
Dram Timing (By SPD) -> (Manual)
SDRAM CYCLE Length (2.5) -> (2)
Bank Interleave (Disabled) -> (4 Way)
Precharge To Active (trp) 3T -> (2)
Active to Precharge (tras) 6T -> (5)
Active To CMD (trcd) 3T -> (2)
DRAM Quene Depth (4 level)
DRAM Command Rate (1T) Command -> (2T)
DRR Voltage (2.70)

His 5v is fine. Most of my system run at about 4.7v as well.

DaveB knows where it's at... the Crucial PC2100 should be able to handle fast timings. The 1T command rate screws everything up bad... 2T is way better stability wise. And make sure you up that DIMM voltage, but at minimum I'd ensure that I had some air running over those memory sticks.

I tried those bold setting and the computer would not boot. I then had to clear the CMOS and start over. What I did notice was my CPU now said 1050 Mhz and the FSB 200 even though I have a 1.4 266 fsb cpu. Whats up with that?

I think its time for a new 450w P/S

[SickBoy]

whoa... at 155 FSB? I take that back... the Crucial would probably not be able to handle fast timings at 155 FSB. You might want to consider lowering your FSB if you're after high memory scores.

Sorry, I guess I just now took a look at your sig and realized you were running 155x10.

Give Dave's response a try. I know he was in touch with doc on his setup. 155 should not be too fast for Crucial 2100 at cas 2.

A sytem reset while oc too high may bring your bios back to default speeds. This might explain the system rebooting to a lower Mhz. Just crank the speed back up using different (and reasonable settings).

[Maximus Nickus]

Buy an Epox and up the memory voltage, my 3x256MB sticks hit 1100/900 @ cas2 150fsb, and theres more!

[DodgeViper]

I am first going to purchase a new P/S. This 300w just does not work well. The 5v rail is jumping from 4.87 to 5.16 and making the computer very unstable. Time for a new P/C Cooling 425.

I just ran Sandra on my Shuttle AK31 r3/Duron system and got:

Int ALU/RAM Bandwidth 747 MB/s
Float FPU/RAM Bandwidth 886 MB/s

This was at 133 FSB and 7.5 multiplier on a Duron. RAM Settings:
Current FSB Freq. (266 Mhz)
Current Dram Freq. (266 Mhz)
Dram Clock (Host Clock)
Dram Timing (Manual)
SDRAM CYCLE Length ((2)
Bank Interleave (4 Way)
Precharge To Active (trp) (2)
Active to Precharge (tras) (5)
Active To CMD (trcd) (2)
DRAM Quene Depth (4 level)
DRAM Command Rate (2T)
DRR Voltage (2.70)

I am going to set my CPU to 143x7 and re-run, see what I get.

SB

[SickBoy]

143x7 with the same memory settings gave me:

ALU/RAM 769 MB/s
FPU/RAM 936 MB/s

Would switching out for my TBird (larger cache) up my scores? Maybe someone else who has a KT266A board teamed up with a Duron can post their scores.....

This was at 140 FSB and 10 multiplier on a T-Bird 1.4/AK31.

RAM Settings:
Current FSB Freq. (266 Mhz)
Current Dram Freq. (266 Mhz)
Dram Clock (Host Clock)
Dram Timing (Manual)
SDRAM CYCLE Length ((2)
Bank Interleave (4 Way)
Precharge To Active (trp) (2)
Active to Precharge (tras) (5)
Active To CMD (trcd) (2)
DRAM Quene Depth (4 level)
DRAM Command Rate (2T)
DRR Voltage (2.70)

These setting on my computer gave me a score of 767/946. I then change only 1 value and that was the command from 2 to 1 and then I posted this score, 802/1004. Next I made one more change and that was the DRAM Quene Depth. I went from 4 level to 2 level and posted this score, 802/1016.

NEXT:

This was at 153 FSB and 10 multiplier on a T-Bird 1.4/AK31.

RAM Settings:
Current FSB Freq. (266 Mhz)
Current Dram Freq. (266 Mhz)
Dram Clock (Host Clock)
Dram Timing (Manual)
SDRAM CYCLE Length ((2)
Bank Interleave (4 Way)
Precharge To Active (trp) (2)
Active to Precharge (tras) (5)
Active To CMD (trcd) (2)
DRAM Quene Depth (2 level)
DRAM Command Rate (1T)
DRR Voltage (2.70)

Here is my CPU/MULTIMEDIA score,

[DodgeViper]

Here is the CPU score,

[DodgeViper]

My 5v rail is on the low side, but after the changes my temps are down. So far running the FSB at 153x10 it seems like everything is stable. I do plan to purchase a new P/S. I just built a friend a new computer and I used the 431W Enermax. I thought that they had fixed their problem with the 5v rail, but his volt are on the down side as well.

I know it would be stupid to ask what is the best P/S to buy because I know the answer. I just do not feel like forking out nearly $180.00 to get it to my door.

[FrozenInHI]

at 140fsb, all memory timings max settings.

You're 5V is low!

Yes T-Birds and certainly Xp's get higher scores as there faster.
I got 125MB/s more with an increase (just via multiplier) of 300Mhz, from 1Ghz to 1.3Ghz.
