Default Platforma old-school (Dothan, socket 478, DDR1) si goana dupa niste "cupe"

Acum vreo 3 ani si jumatate, am intrat in posesia unei platforme mai exotice, placa de baza, un Asus P4GPL-X, fiind una dintre putinele care permitea utilizarea procesoarelor socket 479 pe platforme desktop. Si cum la ora aceea procesoarele Dothan (Pentium M cu 2MB L2 cache) erau cele mai rapide clock / clock, Asus cu al sau CT-479 (adaptorul ce permite folosirea procesoarelor socket 479 pe placi cu socket 478) au starnit interesul entuziastilor.

Acum vreo 4 ani, Micutzu, Sang, Xwoodoo si alti cativa au incercat sa doboare WR-ul la 3D Mark 2001 folosind un Pentium M 780 si placi video Ati (X1800XT daca nu ma insel). Au fost foarte aproape, sarind de 50K, dar fiind in cele din urma depasiti de Dothan-ul lui Hypro 5 (daca nu ma insel).

Platforma folosita de minte contine pe langa Asus-ul mentionat anterior (Asus P4GPL-X Rev 1.03, modata de Sang sau Micutzu), un procesor Pentium M 750, adaptorul, un cooler Scyhte Katana cu un Panaflo L1A 92mm pe el (penibil, stiu), 2*512MB Corsair CMX512-3200C2Pro v4.1, o sursa Antec TP 380W, o placa video PCI Matrox Millenium G450 16MB , 2 fanuri de 120mm si peste 3000 rpm si alte cateva nimicuri.

Am (re)inceput testarea platformei aseara, in camera la ~25C. Dupa 2 degete arse (picase modul de VCCA, asa ca aveam doar 1.6V) si batai de cap am reusit un SPi pe la 2850MHz.

Azi am pus platforma la geam ... si initial nu am fost prea multumit de evolutia frecventelor. Asa ca am marit voltajul la procesor la 1.8V, am crescut VCCA-ul si parca a inceput sa fie mai bine.

Pe la ora 10.30, cand am inceput, am zis ca pe la 12.00 termin. Ar fi fost bine ... Dupa vreo 10 ore de benching cu geamul deschis la 1m, cu Delta si Sunon-ul care sufla mai ceva ca AC-ul ( = durere de cap de cateva ore), am reusit sa depasesc cateva dintre obiectivele initiale ...

Pana acum am reusit asa:
CPU-Z: locul 5 - 2945 MHz http://valid.canardpc.com/show_oc.php?id=1566673
PiFast: locul 3 - 41.38s
SPi 1M: locul 10 - 25.704s
SPi 32M - nimic (adica scorul vechi ramane pe locul 3) - 25m11s750
wPrime 1024M - locul 3: 1834.953s
wPrime 32M - locul 2: 56.531s

PS: Vin si pozele imediat.

Dupa mai bine de 12 ore si un loc 1 - 1816.406s @ 2948MHz in wPrime 1024M. SPi 1M n-a mers nici macar la 2939MHz pana la capat, iar "mizeria" de PiFast a murit cu > 100MHz mai jos.

Si un CPU-Z @ 2973 MHz. N-a fost sa fie > 3000MHz, dar va mai fi si o data viitoare.

Azi n-a mers prea bine, dar am dat niste bench-uri 3D.

Dothan M750 @ 2804 MHz (200*14)
Asus P4GPL-X @ FSB 200
2*512MB Corsair CMX512-3200C2Pro @ DDR400 2-3-2-5
Leadtek 8800GT 512MB @ 725 - 738 / 1890 - 1944 / 2106 MHz

Rezultate:
3D Mark 2001 - 40027
3D Mark 2003 - 35563
3D Mark 2005 - 13345
3D Mark 2006 - 7888
Aquamark 3 - 109333

Cu putin noroc [frig si racirea de pe procesor schimbata], probabil ar putea iesi 42-43K in 2001, 36-37K in 2003, ~ 14K in 2005 si ~ 8K in 2006.

Din pacate, nu pot pune Thermaltake Big Typhoon-ul pe procesor din cauza adaptorului minune (CT-479) care acopera 2 suruburi din cele necesare montarii ...

Mai incerc asa. Sa vad daca pot pune cumva TRUE-ul pe procesor. La 1.8V am ~50C in BIOS la temperatura camerei deja si nu risc. vCCA-ul nu merge mai mult de ~ 3.44V.

Am incercat sa profit de temperaturile ceva mai joase, dar fara prea mult succes - am salvat validari pana pe la 3033MHz, dar se pare ca toate sunt corupte.
56.25s - wPrime 32M @ 2975MHz
Screenshot cu temperaturile @ 3000GHz si ~1.83V in idle.

Dupa mai multe teste, se pare ca placa merge 1:1 cu memoriile (Corsair CMX512-3200C2Pro Rev. 4.1. - Samsung TCCX) pana pe la FSB 233 2-3-2-6 si FSB 255 2.5-3-3-7.

1) Dupa multi peri albi si si mai multi nervi in ultimele vreo 7 saptamani, un scor in SPi 32M - 25m02s047 @ 2809MHz (216.1*13, DDR432 2-3-2-5). Am avut si run-uri care dupa 2-3 loop-uri duceau spre 24m30s ... dar au crapat invariabil din cauza RAM-ului sau NB-ului

2) Se pare ca validarile serau salvate fara extensie. So ... validare @ 3031 MHz.
http://valid.canardpc.com/show_oc.php?id=1655794

3) FSB 261 cu memoria 1:1 @ DDR 522 2.5-3-3-7. Din pacate, SPi 32M n-a tinut nici la FSB 250 ...

Work in progress. Obiectiv S.F. - 24 minute in SPi 32m.

Din pacate, Tudore, e mai complicat decat pare. Nu pot schimba racirea de pe CPU (un amarat de Scythe Katana), pentru ca adaptorul acopera 2 din gaurile de montare a coolerelui. Am incercat sa pun deasupra un TRUE, dar nu face contact bine ... Am pus fan de 120 CFM pe radiatorul de la cooler si mare lucru n-am scos. Un Vantec Tornado ar fi mers la fix, dar nici ala nu facea mare branza pentru ca radiatorul e praf.

SPi 32M mai sus de 2.82 - 2.83 GHz crapa rapid chiar daca am -2C pe CPU in idle. Cheia este FSB mare 1:1, dar n-am reusit 233*12 nici cu 2.5-3-3 desi am dat SPi 1M la >260MHz. Am incercat 255*11, dar n-a vrut nici cu 2.5-4-4 ...

Sub 25m ar trebui sa iasa, dar 24m (~24m0s) ...

Scorul asta cica-i al doilea cu Pentium M pe aer. Primul este pe la 3070MHz, iar cele care mai apar pe acolo, din ce am vazut eu, au core Yonah, care-i alta mancare de peste ...

Brainiac , am un kit de memorii Corsair 2x256 Mb , CMX256A-3200LLPT (2-3-2-6) , daca doresti ti le pot da pentru teste in cazul in care consideri ca te-ar ajuta. Bafta in continuare , .

Cu PCIe @ 133MHz am ajuns pe la FSB 27x MHz. Momentan ma "joc" cu PCIe @ 135MHz, ca la 140 sigur nu vrea. FSB-ul maxim pare legat de frecventa PCIe, daca am bagat bine de seama, desi de la 120 la 135 n-am mai castigat mare lucru.

Update: 24m44s - SPi 32M @ 2824MHz, DDR470 2.5-3-3-8.
25.468s - SPi 1M @ 2888MHz, DDR 512 2.5-3-3-8.

Multumesc, err0r, dar nu stiu daca ma ajuta 2*256MB. Sigur sunt mai lente in SPi 32M (si 2*512MB pare mai slab ca 2*1024MB). Ai idee cumva cat "duc" ?

Se pare ca merge nitel mai bine dupa ce-am scazut vCCA-ul nitel: de la 3.46V (maximul masurabil/setabil, ca minimul este sub 1.60V ) pana pe la 3.33V.
