Cool 512MB HIS X1800XT PCI-E + AMD64 Opteron 170 Dual Core Review adventures

With ATI Catalyst 5.12 being released and optimised for dual core cpus, I decided to swap my 512MB HIS X1800XT PCI-E card over to my Opteron 170 dual core cpu rig

You can re-read the 512MB HIS X1800XT single core results with Opteron 146 at http://i4memory.com/showthread.php?t=1842



System

Opteron 170 CCBWE 0544XPMW cooled by Corsair Hydrocool 200EX
DFI NF4 UT SLI-DR R.AB0 11/14-3 bios
512MB HIS X1800XT with Cat 5.12 drivers
4x 80GB Hitachi 7K80 SATAII Raid 0 OS drive
1x 250GB Maxtor Maxline Plus II PATA
Pioneer DVD Burner
Floppy drive
650W Silverstone SLI PSU


WinXP Pro SP2
NF4 6.53WHQL chipset drivers

Using 2x 1GB OCZ PC4000EB Platinum 3-3-2-8 rated memory
@3-3-2-5 7-14-2223 at 2.64v vdimm

===================================
Overclocking X1800XT
I'm overclocking and changing voltages on X1800XT the same 5 step method i used on single core Opteron 146:
  1. In service manage in windows disable ATI Smart and ATI Hotkey services and reboot pc. You loose temp reading in CCC but can use ATI Tool to view temps.
  2. Use X1800 Oc'ing tool and set 3D desired clocks using the 2D panel by TYPING in the clocks DO NOT use slider!
  3. Use ATI Tool to only verify and view the 3D clocks are set correctly. So should be same as what you set in X1800 Oc'ing tool.
  4. Whenever you set the mem clock, remember to set the GPU core clock again, or it will fall back to lower clocks and when you set the GPU core clocks again, remember to set the mem clock again, or the same will happen.
  5. Setting voltages, OC'ing tool reports wrong voltages so DO NOT use OC'ing tool to set voltages, use ATI Tool to set voltages. Example, GPU voltage reported in ATI Tool is 1.275v will show in OC'ing tool as 1.3v. Set ATI Tool GPU volts to 1.3v will show OC'ing tool at 1.325v but the real voltage measured by DMM is closer to 1.3v as set in ATI Tool.


===================================
Benchmark results

Opteron 146 @ 10x200HTT = 2000mhz with Cat 5.11 drivers

vs

Opteron 170 @ 10x200HTT = 2000mhz with Cat 5.12 drivers


3dmark05
- Cat 5.12 on Opteron 146 resulted in 50pts less in 3dmark05 and 100pts less in 3dmark2003 at same clocks as Cat 5.11 drivers when tested.
- Opteron 146 tests used 2x 512MB Gskill PC4400LE TCCD 431 2-2-2-5 7-14-2222

@621/747 = 8,636 vs 8,911 (+275pts increase with Cat 5.12 /Dual core cpu)
@680(675)/800(792) = 8,986 vs 9,381 (+395pts increase with Cat 5.12 /Dual core cpu)
@710(708)/802(801) = 9,106 vs 9,572 (+466pts increase with Cat 5.12 /Dual core cpu)

3dmark2003
@621/747 = 16,368 vs 16,735 (+367pts increase with Cat 5.12 /Dual core cpu)
@708/801 = 17,698 vs 18,111 (+413pts increase with Cat 5.12 /Dual core cpu)

----------------------------------------------------------
Opteron 170 @10x260HTT = 2600mhz at 1.392v
2x 1GB OCZ PC4000EB Platinum @260mhz 3-3-2-5 7-14-2223

3dmark05
@621/747 = 9,284
@708/801 = 10,205
@756/900 = 10,965

3dmark2003
@621/747 = 17,847
@708/801 = 19,425
@749/900 = 20,535


----------------------------------------------------------
Opteron 170 @10x280HTT = 2800mhz at 1.552v
2x 1GB OCZ PC4000EB Platinum @254mhz 3-3-2-5 7-14-2223

3dmark05
@621/747 = 9,365
@708/801 = 10,310
@756/900 = 11,058


----------------------------------------------------------
Now compare that to these oc'd single core Opteron 146 cpu results
----------------------------------------------------------
Opteron 146 CAB2E 0540FPMW @10x280HTT = 2800mhz at stock vcore
2x 512MB Gskill PC4400LE @280mhz 2.5-3-3-6 7-14-2222

3dmark05
@621/747 = 9,235
@708/801 = 10,163
@742/891 = 10,795

3dmark2003
@621/747 = 17,707
@708/801 = 19,169


----------------------------------------------------------
Opteron 146 CAB2E 0540FPMW @10x300HTT = 3000mhz at 1.408V
2x 512MB Gskill PC4400LE @272mhz 2.5-3-3-6 7-14-2222

3dmark05
@621/747 = 9,287
@708/801 = 10,221
@749/882 = 10,869

3dmark2003
@621/747 = 17,945
@708/801 = 19,449
@735/882 = 20,328


----------------------------------------------------------
Opteron 146 CAB2E 0540FPMW @10x310HTT = 3100mhz at 1.536v
2x 512MB Gskill PC4400LE @282mhz 2.5-3-3-6 7-14-2222

3Dmark05
@621/747 = 9,321
@749/882 = 10,915

3dmark2003
@749/900 = 20,784


----------------------------------------------------------
Opteron 146 CAB2E 0540FPMW @10x313HTT = 3130mhz at 1.568v
2x 512MB Gskill PC4400LE @283mhz 2.5-3-3-5 7-14-2212

3dmark05
@756/900 = 11,049

3dmark2003
@756/900 = 20,860

----------------------------------------------------------

Well for 3dmark05 at least for max Opteron 146 /170 cpu clocks and @756/900 clocks for 512MB HIS X1800XT stock heatsink, the difference is ~9pts to the dual core Opteron 170

3dmark05 compare urls

Opteron 170 @2800mhz = 11,058

vs

Opteron 146 @3130mhz = 11,049

Posted this on another forum so thought i'd add it here:

here's my take on single vs dual core and 512MB 7800GTX vs 512MB X1800XT

- 512MB 7800GTX clock for clock is faster than 512MB X1800XT, but from end user such as me, X1800XT can clock higher than 512MB 7800GTX out of the box no volt mods and with stock heatsink. Once clocked higher X1800XT can pretty much close the gap on 512MB 7800GTX making the US$200+ price difference pretty attractive for 512MB X1800XT especially with availability right now.

- AMD64 dual core opteron cpus are like 512MB 7800GTX and AMD64 single core opteron cpus are like 512MB X1800XT in that clock for clock in 3dmark and some pure gaming scenarios eventually, the dual core opteron is faster than single core opteron. But single core opterons overclock alot higher. Average dual core opteron clocks between 2.45ghz to 2.75ghz while average single core opteron (from my testing does 3000mhz to 3100mhz).

So on average single core opteron for pure gaming/3dmark benchmarking can close the grab pretty much at 3-3.1ghz. Of course if you using it as 24/7 every day machine that dual core would be alot better.
