Precision M4500 Owner's Lounge

NVM i just found a way to do it

 

So share ... what was it?

 

oh i didnt know anyone would need the info but here it is:

so like anyone else, i wasnt able to oc using nvidia performance utility.

so what i did was i downloaded gpu tool to oc.

at first, they wont let you oc your clock or memory speed. so you have to AT FIRST significantly increase your shader clock. basically, find the max for yo shader clock first. after like 50mhz+ oc in shader clock, you can actually now increase the core clock and the memory clock. you will see how it goes from then.

Seems like people first try to oc the core clock and the mem clock and when they both fail, dont even bother to oc the shader clock. i have the latest drivers i think.

results for 1800m:

665
965
1600 (i know that is a HUGE oc but it works)

with my quad core i7, runnin furmark and prime 95, with stock paste, i get like 76-76 max for gpu and 80-81 max for two of my cores in cpu. so i guess the temps are decent. im going to apply artic 5 soon.

i got 8950 in 3dmark06 with 820qm and 1800m. it was like 19.75% increase from stock clock.

good luck! and share your results

FYI: if your drivers crash due to too high clock, everytime it crashes, you need to restart your computer. as you can see from sensor of gpuz or so, once the driver crashes, the core clock is stuck at 405mhz and so on, until you restart your computer. so it does take a chunk of time.

 

can anyone PLEASE tell me if m4500 will allow RAID 0 of two hard drives?? im thinking of getting the hard drive into the optical drive slot with that caddy from emodeus.

basically, does it support RAID 0 when i hook up the 2nd hdd using the optical drive bay???

Thank you to anyone who can help me out!

 

I am new here and have bought an m4500 recently and I'm very happy with it except for one thing. Do you also experience a chirp like noise on your units if you drag the brightness slider up and down very fast in Windows power options. Sort of like coil whine.

Just turn off the ambient light sensor if it is on and put your laptops brightness on full and then instantly dim it to minimum. When this happens my unit emits a slight noise from the left hand keyboard area for a split second.

Does yours do the same by any chance? I also noticed that the brightness adjusts very suddenly in steep increments rather then smoothly like on my dad's HP laptop.

I hope this is the right place to ask as this is the owner's lounge.

 

Note that I'm not actually running a RAID 0, but I do have the Newmodeus caddy. I have an SSD as boot drive and put the original 500GB HD in the optical bay. When I boot the PC, I get a menu from Intel that enumerates both my HDs and has an option to go into a configuration screen to configure stuff like RAID. So yes it supports this option. You'll probably need to make sure the Intel drivers are installed. Also note that if you plan to use SSDs for the RAID, you actually lose TRIM support even if you run under Windows7

 

thank you for your response. what intel drivers are they?? are they ones already installed from factory??

and do u think two 7200rpm drives in raid 0 is as fast as a single ssd?

also does your 2nd bay fit your laptop perfectly??

Thanks in advance for more answers.

 

Haven't looked too deep into this. They came factory installed, but I reinstalled Win7 from scratch afterwards, and basically immediately installed the Intel drivers from the DELL M4500 download pages. Never tried without them but I SUPPOSE you really need them for this.

Throughput-wise you could get close, but not in terms of access time. I bought my SSD specifically to shorten boot time and to eliminate tearing out hairs when launching multiple apps at the same time. Especially for that last purpose I don't think RAID 0 with traditional HDDs will touch the SSD experience.

However I've seen very positive reports about the Momentus XT hybrid HD. At some point I really started to consider that one since it seems to offer an attractive compromise between SDD and HDD.

Haha... Very appropriate question! In the sticky thread in this forum you'll find a message from me about experiencing that it actually did NOT fit (or more accurately: it fit ONCE, and then never again . But I have to say that Newmodeus customer support reacted fast and immediately shipped a new caddy (no return necessary) and all is OK now.

 

Ha thanks for the quick reply

 

The Samsungs are not as good as some of the competition, I went with Intel X25M and started from scratch: The SSD Relapse: Understanding and Choosing the Best SSD - AnandTech :: Your Source for Hardware Analysis and News

However, an all-new Samsung drive is on the way so it's not all bad. And any modern SSD is better than a HD nowadays.

I also didn't want to have a drive Dell gave me because of past issues/restrictions over upgrading the firmware, which I also experienced with Sandisk drives with their very first SSDs.
