Overview
Last week i had the opportunity to play with some of the latest hardware in the PC Industry. I was given an engineering sample of Intel Core i5 665K ES cpu and a Nvidia 465GTX graphic card to play with. Due to my busy schedule, i was unable to provide full-length review on both the cpu and graphic card. So i decided to run some simple benchmarks targeted to OverClockers. As always, let the pictures to the talking.

UPDATE 17-07-2010
After looking at the benchmark scores i obtain were kinda slow, i sent a feedback to MSI Malaysia. And after discussing with their engineer in Taiwan, i was told that the official BIOS v1.1 used does not fully utilize Intel K-Model processors. Therefore i decided to use the Beta Bios for another round of re-bench. For this round of re-bench session, i tried out Super Pi 32M first on Windows XP SP3 environment followed by Everest Ultimate Cache and Memory Benchmak, 3DMark 06 and finally 3DMark Vantage on Windows 7 Ultimate 32bit environment.

Intel Core i5-665K Introduction
Recently Intel just released the K model processors with unlocked multiplier. Currently there are two LGA1156 models, Core i5-655K and Core i7-875K. No doubt that these K model processors are now the main interest in the OverClocking Community. OverClockers now do not need to spend large sum of money to purchase the Extreme Series processors to enjoy the fun of OverClocking an unlocked multiplier processor.

Testbed

Processor: Intel Core i5-665K ES
Mainboard: MSI Bing Bang Fuzion
Memory: Corsair XMS3 TR3X6G1600C7 (2GB x 2)
Graphic Card: MSI N465GTX Twin Frozr II
HDD: Western Digital 80GB Black Caviar
Power Supply: Antec CP-1000
Heatsink: Scythe Grand Kama Cross
Operation System: Windows 7 Professional 64bit

Intel Core i5-655K
i5-655K is relatively easy to OverClock. With the unlimited multiplier option, BLCK is no longer an issue to higher cpu clockspeed. As for this test, my intention is just to hit 5.0GHz clockspeed and it was done within minutes. As my main priority is not on the memory, the ram is kept at the rated speed for all of the benchmarks done.

MSI N465GTX Twin Frozr II
Since this is a OverClocking Test, i carried out the testing in a very simple methodology, stock-speed vs oc-speed. With the MSI Burner tool, i could adjust the Core Voltage. Therefore, i set a core voltage limit to obtain the highest core and memory speed of the card. The core voltage was set to 1075mV while CPU is set to 4.0GHz clockspeed.

Conclusion
Intel i5-655K: It's yearning for Extreme OverClocking.
Nvidia N465GTX: Price is very close to ATI 5850 but the performance is not.

Special mention to MSI, Corsair, Antec and Intel

nice setup there and the rams u have there

Holy cow...straight away to 5Ghz....o.O"

and the temperature would be?

sup3rfly: all normal rams, haih... none can do 2000mhz 7-7-7.

shinjite: it's kinda normal if you look around reviews on the net. most of the 655K proc is able to do that on air, 1.45v - 1.5v.

BigSaver: hrmm... as i'm only doing CPU Validation, i don't really care about the cpu temp if you are asking me. i only focus on the voltage needed for 5.0ghz. but according to bios H/W Monitor, it's around 40 degree, 1.47v with the Scythe Grand Kama Cross + 800 rpm fan. lol, this reminds me the only time i look at the temp is while doing stress test which was years ago. and which benching LN2 with coolice. my job is to 'LOOK AT THE THERMOMETER" and pouring the LN2.

nice i can say, 5ghz on air.like the i3 series.most can do around 4.Xghz close to 5ghz on air too.

btw the gtx 465 no chance to unleashed the "470"?

This post has been edited by BigSaver: Jun 25 2010, 12:41 AM

well the amount of mem is more than waht i got already

BigSaver: unfortunately nope. there's only one GPU chip which is able to flash to 470GTX.

sup3rfly: none is mine. lol.

Such high clocks, CPU and RAM, yet your everest memory bench is terrible, why is that?

Ram setting is not optimized
@Sanko,hmm seem like GTX465 performance is a bit lower then what it should be

OC4/3: ya, i did alot of testing on the VGA actually. i was wondering how come the score is so low. i checked reference in hwbot and couldn't come close to them even though the core and memory is almost the same. here is my findings.

1. PhysX is disabled.
2. Dual Core CPU.

But i have to admit that my FPS is really low compared to others. and to be honest i'm still looking for the answer. for CPU my test took me 1-2 hours only. while the vga took me 2-3 days.

I'm not quite sure is it the OS is giving me the problem. I reinstalled 3 times with the same thing. my Super Pi result is even worst. it hang 1 sec before the last loop. i'm going to test this rig again with XP environment and a new bios which will be released soon enough.

Cause i was comparing to my own pc which is a E8600@4.2ghz and GTX260@SOC Default clock,score is 17.6k

OC4/3: thanks for your insight. PhysX is enable for your score?

i'll re-run the 3ds tonight. during my test although cpu-z is detecting the speed as 4.0GHz, but futuremark 3dmark06 is detecting it as 3.8Ghz if you see the ss. in 3dmark06, higher cpu frequency will result in higher SM2.0 and SM3.0 score.

my testing also shows that 3dmark06 couldn't read multi beyond 24. while comparing your result to mine, both using 2 dual core but mine is around 3.8GHz while yours is 4.2Ghz. however if judging from the comparison between the 2 cards, 465GTX should be the winner in quite a margin. so the physx and cpu definitely won't be the main issue here.

PS: lol, used my housemate ID. using P1 package only allows 1 user. sigh.....

futuremark doesnt read turbo multi

it only reads bios set multi

- again wrong post, using housemate ID -

cstkl1: thanks for your info. but i remember clearly the turbo mode is disabled. managed to use 25 multi because of the unlocked feature of the cpu. will check later. had issue with the monitor, sigh....

Huh, can you explain?

Settings were 7-7-7-20 @ 800MHz for the 655k. With an 860 running at slower cpu clock and 7-7-7-20 @ 700MHz I can hit double the bandwidth of the 655k. Seems to me like the memory might be bottlenecked by the 655k. Maybe it's like this with Clarkdale.

Zibel: looking at the results, i'll carry out another session of testing with the new BIOS slated around beginning of next month. according to MSI, the current bios is not optimized for K series cpu yet.

AFAIK,physx does not affect 3dmark06 result
I don't really know what wrong but give it a shot with windows xp,hmmmm

Hope a new BIOS helps. Thanks for the review.

woahh! syiookk! nicely run!

Luv ur ram'ssss~

As promised, re-bench using beta bios which gave 'acceptable' results. and finally i managed to run my favorite benchmarks, Super Pi 32M. using previous BIOS, even running 1M the final loop will hang for a while.

physx did affect ur 3d06 results... not a great diff... says 100 - 300 pts... thats what i experience b4...

IIRC some old driver does gave some boost to 3DMark06 through pyhsx. but now it rarely does.

it did... latest driver... lol..

Now this result is more in line with expectation

Better but still not impressed with the Clarkdale RAM results. It's like the dual channel really doesn't seem to be doing much. I'm wondering if you took one stick out and ran single channel if the RAM bench results would be fairly close to the dual channel results.

Lynfield seems to do much better with the RAM, maybe they'll give you an 875k to compare.

Nice review, and great pics.

Hey isnt it the big bang?
It's still too early to play with 665K when the bios is imature

Added on July 19, 2010, 7:04 pmI wanna see ur cpu config during Pi

OC4/3: Thanks.
Zibel: I believe Clarkdale is quite a distance it.
owikh84: CPU Config? you mean the CPU Performance through Windows Task Manager?

it's actually in ur BIOS hehe.
Nvm small matters

hrmm... maybe you can specify what you want to know. it's my pleasure to share anything.

brother sanko.i will have 675K ES to testing soon.hope to shared with u.taiwan friend hit to 5GHZ Air cooled....

...and i5-665K in the market is still unlocked multiplier, right?

yeah.... its unlock even retail... same as 875k... both k type are multi unlock....

Vtec(Rock): nice to hear that. in anyway i could help i would like to. hehe...

yeah.enjoy the oc!!
1st wan try 875K 1.1 unit is own use.2 unit also sell no choice lar.ask friend send me 675K lor

Vtec: it's quite easy to clock 655K. the only problem for me is mainly the BIOS. but eventually it's ok now.
